Hello,   I tried to do a node analysis with a resistor matrix. The input of the voltage matrix should be variable, therefor I introduced an array with voltages. After the solver I get an error "This value must be scalar or a matrix.". What must I do to get the rigth result, doing the calculation without array works.   Thanks  

I selected AK Jairath textbook because it goes back to 1992, 30 years ago, and its closer to that classic style of problem solving textbook. 2nd edition in 1994, and reprinted in 1996.Solutions & Problems in Control System. May not be in circulation now. Its a smallbook. Concise, similar to Schaums (Supplementary), its not a main textbook.   Chapter 1 is Transfer Functions. All the problems in chapter 1 are made up of R L Ccomponents. So this was in line with my/our starting plan to stay within the electriccircuits corridor. First keep things simple. So if you asked why, that's the reason Iselected this chapter. We did some theory-examples in transfer function at end ofPart B, so its best to do them first since these are fresh in minds. This is part of Part 3C (Electric Circuits I) which here can be independent (on its own).Got an opportunity to work with RLC components in the transfer function andsecondly control systems context, why waste it. So I did these few ex

Continuing from Part 2-B, this is Part 3 - A. This file starts on the basics. Some discussions, and examples. Answers are there. May not be as in depth as most students like. So refer to your engineering mathematics textbook. Completed a few examples problems and plots to get a general understanding on this subject matter. Please refer to electrical engineering textbook used in college of engineering or pick one of the shelf.Schaums Chapter 8 Contents Covered in Part 3A:8.1 Introduction8.2 Series RLC circuit8.3 Parallel RLC circuit8.4 Two-Mesh circuit8.5 Complex frequency   Continuing with Part 3B.Schaums Chapter 8 Contents Covered:8.5 Complex frequency8.6 Generalised impedance (R L C) in s-domain.8.7 Network function and pole zero plots.8.8 The forced function.8.9 The natural response.

Hello everyone,is there any way to get the correct symbolic answer? from the calculation, it turns out that Wolfram's answer is correct, and that of M15 is not; see photo:

Dear sir,   Now I am solving a design optimization problem using Mathcad prime 6.0 through python API. I uses comtypes library to deal with API programming in my Python code.   In python code, I can set a single variable easily and vice verse. However, I could not set a matrix and get it from Mathcad.   I really love to exchange variables which whether it is a real single variable or matrix between Python and Mathcad.   I could not find any solution method for this trouble.   Please help me with this issue. I really want to make them exchangeable for reproducible research work. It is not commercial but academic.   With my best regards,   JW --------------------------------------------------------------------------------------- The following is the python code to call and set matrix in Mathcad. Two functions are defined. The first(set_element) is  to set the elements of the matrix in Mathcad but the second(get_element) is to get the element of t

Like VBA or any other special function.

Just got an error on a mathcad calc that says it is corrupted. Can this be recovered ?

Whenever I try to install MathCAD off of a CD or off of the downloaded application, I get the following error message. "Module C:\Program Files (x86)\Mathcad\Mathcad 15\tabler.ocx failed to register. HRESULT -2147010895. Contact your support personnel." Any suggestions on how to fix this?  

Hi,I use the error message function to inform me about some errors in a few functions. At the same time I use on error operator to get already calculated results in a loop. Without it I can't see what is happening (I can't get already calculated results). I want to find out which function causes an error without using debug mode. Is it possible? Simplified example without loop is attached.

can anyone help me and send me a converted file for prime 6 since I have only prime 6 installed and can't convert. tried to install version 15 and it won't take my prime 6 licence file, so i uninstalled it.

Hi   I have three variables in Inductance (L) value calculation for buck boost converter - Input Voltage, Output Voltage, Output Current. All three can vary. I would like to plot L value as a function of these three to determine the Worst case inductance requirement. In the attachment I have attempted 2D graph but how can look at sensitivity of L value this with 3 variables?    Regards Prasanna

Hello there, I have a drawing in autocad. Is it possible to connect both mathcad prime and autocad so that if i change my value in mathcad then the value in autocad change?   Thanks.

the tan of 45° = 1 What kind of function or formula should be needed in ptc to invers 1 into 45° ? thank you  Marco  

Dear Mr. Werner_E, & All friends in Mathcad Prime. Could you explain me, how to plotting array pile as show below picture to me please ? Thank you all friends in advance.      

Hi all friends, please help to explain me. how to plotting rectangular equation array to matrix ?

I am writing a system of equations and I want to plug values in for my remaining unknowns from a range of values and graph the resulting function. I actually want to have several variables be range variables while known variables are just one value. Do I need to build filler matrices for the single value variables to match up the matrix size or can MathCAD see the single variables as scalars to multiply by the matrices? I want to solve the system of equations with a brute force method instead of solving at many different points to cancel out variables. Any help is appreciated. I will be searching the help files until I get some help figuring this out.   PS in the example I set a range variable of step size 1 N/mm to 100 N/mm and have the other variables defined as single value variables but I get the error message "This value must be a scalar or a matrix"

Hi Everyone,   New MathCAD 15.0 user here having trouble resolving a “no solution was found” issue in the attached file. I'm trying to solve the equation for "y".   "x" is the independent variable and is greater than zero. All the Greek letters are constants that are also greater than zero.   From the looks of it, the solution should be some sort of Lambert-W function, and since everything is positive, the solution shouldn't have any imaginary component.   Any help would be appreciated!

Hello to all Mathcad professionnals I need your help again.   I need to calculate a drive torque for a wheel climbing a ramp. i can calculate this,  but my worksheet is not elegant and is heavy 😥 (probably, i'a m using matchad programmation not correctly)     Here is now i do The ramp is cylindrical profil in first time   now, i dicotomize a ramp ( arc lenght)   In second time. At this step, this is a mechanical problem I assume the ramp angle is simply a/2 . In fact, the ramp (red line, on the picture) is the tangent equation at the circle. the first point where we calculate a tangent is calculate with polar coordinates from dicotomized values.     I think my result its Ok but i want more 😁   I want calculate all Traction forces and all associated torques for all dicotomized value. in one program ? and i want to draw all result at this moment i am lost, can you help me thank   attacher P6 file  

1) I know four Prime numbers from Pi without point. Do you know more? 2) How we can find this numbers not manual - by programming? 3) It the problem correct and solved?

I am making the attached Mathcad 15 worksheet (Ring q Loading - Sin-Tangential Resistance - Uniform Varying Load.xmcd) available to anyone that needs such a tool. This worksheet is one of several that analyzes a structural ring stiffener (or bulkhead) given a general radial load pattern resisted by sine-tangential forces in the adjacent shell.  This is a common structural model fully explained in Roark's "Formulas for Stress and Strain" (any edition). Since I am new to this PTC community forum, I am using this worksheet as a test.  If this works, and/or the reports back from other members of the forum indicate an interest for other types of loading conditions, I will continue to post them. While this problem can be modelled using Finite Element Methods, the process is labor and time intensive, and would require frequent model alterations to converge to an efficient design. Also, the proper FEM boundary conditions needed for the sine-tangential resistance are very, VERY!, tric

Hi the MathCad community, once again I ask for help I want to calculate the wheel torque necessary for climbing a circular ramp. I can calculate this, but it's not elegant and heavy, because i don't use mathcad programation correctly.   first:   in second time, i dicotomize the arc lenght with step parameter      Now, this is a mechanical problem, i assume the wheel goes up the slope. The slope is the tangent equation at the coordinates point (from dicotomize function) And the slope angle is simply a/2    i think the result is OK   But i want more 😁   I want calculate all traction forces T and all torque C  for all dicotomized value in a (one ?) program. and after draw the result 🙄 and i'm lost to do this🤔   In the second step (after) : i have 2 drive wheels, the P force( f=ma) are apply in center line who link 2 wheels i want to calculate Normal Force (N) variation. Because, the wheel climbing ramp, the normal force are modi

Hi everyone,   I am trying to work in an exported file from Mathcad 15 M050 to Prime 6.0 I am working with symbolic expressions where I used prime variables to define velocities of an angle. In Mathcad 15, I use CTRL+F7 to add the apostrophe to the variable, but in Prime 6.0 it doesn´t act the same way. I tried to use the one in the "Operators" menu, but it doesn´t operate the symbolic expression the same way.    If anyone has a possible solution, I will appreciate it. Thanks in advance. I´ll add some images of part of my file, in Mathcad 15 and Prime 6.0  

Hi everyone, when I try to make a Mathcad15 object in Word, I do not get my calculations through. (See image 'Word', my 'c' isn't calculated) I already tried to reinstall Mathcad15 but that didn't work out. It's a very simple test calculation that doesn't go through. (see image) What I already noticed is when I use 'paste special' it doesn't show 'Mathcad object' but just 'Object' and I can't make an object link, but no idea if that is part of the problem. (see image) I also want to make it a link so I can refresh these calculations in my Word file. There are no issues on my collegues PC. Anyone had a similar issue or has a solution?   Thanks in advance, Arne
