Mathcad

Hi I have a problem, i don't find why ? (equations for intersection point of 3 planes) Probably syntax error ???   in first solve block, i have copy / paste equastion of symbolic evaluation for plane equation

Hi all.   I have some files that read data from text files and then does some calculations.   In some instances that data may be moved which basically "kills" the calculations.    How can I "embed" the data into the Mathcad file so that it becomes self contained?   Do i have to copy the data into a matrix or table or is there another way?   Thanks.  

Do you know how a catenary lies on the cone? Without friction!  

Hi, I have a rather large matrix (1100 x 40) from which I tried to filter out the data that have NaN content, but to no avail. When I searched for the problem in my code I found that the the filterNaN function sometimes didn't filter NaNs although the entite columns was filled with NaN. I tested this by checking whether the value is indeed NaN, which it is. Checking whether the same value is a scalar returned also a positive?!?  (see attache sheet which contains a subset of that data). Does anybody have an explanation for this contradiction and/or can tell me how to avoid this? Thanks Raiko

How to find upper and lower envelop of the signal ? please check my mathcad file !

What's the purpose of a sorting algorithm, if it doesn't work!? Prime 4: And this is what it could (should?) be:     Luc  

Hi I have a couple of question to the explicit function: Question 1: How to avoid that explicit writes long units descriptions like seen in the attached file? - How to avoid it taking more space than a full page width?   Question 2: How to avoid that explicit writes 500 (V*A*10^3) instead of 500 kVA?.   Kind regards Benjamin

I need to convert an old mathcad .mcd file to the newer .xmcd format. I have mathcad prime 4.0, but the button to do the conversion is grayed out.

Hi everybody! Primary question is: How could one define a complex number? I tried it  assigning  Re(C):= Formular1    Im(C):= Formular2 After that I assigned:  G:=Re(C) + Im(C) This shouldn't be neccessary, because a complex number is defined by its components. But it is obviously neccessary. Without that a plot doesn't work. I attach the whole working sheet and the Input data of the load in the time Domain. Thanks in advance! Udo    

In Mathcad If I have 3 functions a, b and c and I whant d to be the biggest out of the three how do I do that? Like:   d=max[a:b:c]=biggest value   Thanks for help

Hello. How can I write these two in mathcad I can not find the symbols?

Hi,   I want to send string value from creo to mathcad, so please can you let me know how we can do this?   I tried by creating model parameter as string but it is not getting transfer so please can someone help.   Regards, Prashant Pandarkar

Dear all,   I would like to solve a linear equation system in Mathcad. The question is how to solve it symbolically. I've already looked in the previous posts but unfortunately I haven't found the solution. I really appreciate your support.   Best Regards.   Enrico

Hello, i would like to plot the inductance current in mathcad. Piecewise functions describe the problem. The piecewise function starts from the value before. How can I do it? Piecewise function with if/else are easy, but how can i save the function value.   Thank you for your help.

Hi everyone,   I am currently trying to insert 8 references (worksheets) into a central worksheet to pull data for a calculation.   Previously, when using 4 references I have not had any errors. In my current calculation, out of the current 8 references, 2 have errors as shown below:   "There are calculation errors inside "......." "   There are no errors in the referenced worksheets, I have also tried to copy the calculation into a new worksheet, restart the computer, re-enter the reference etc.   Has anyone else had this issue before?   Could it be due to there being too many references?   (I am using Mathcad Prime 3.0 and have tried this in 4.0)   Thanks,   Henry  

To all,I am looking for a way of writing an ODE in matrix form and solve it (in a matrix form). I am using a 2- dofs system, please see attached.Can the ODE be solved as it written? I can find plenty of info/tutorials, etc on ODE but never with the matrix notationThanksRegards

Hello.  Somebody there knows how to write mass flow rate like the dot on the m.  and the same for Volume flow rate the dot on the V?

Why I have an error by ode solution? Same ode in Prime has no error! See please Mathcad 15 sheet in attach!

I have been a long user of Mathcad, back when it was a DOS program.  Currently I am using v15 but am planning on moving to Prime 5.  On some of my project I have to load six or more spreadsheets.  The multiple spreadsheets are loaded at the same time, via nested matrix.  Each cell has a READEXCEL for each case.  The individual matrix is accessed using the indexes.  I have two questions:   1. Will Prime support a similar method of reading multiple spreadsheets? 2. What is the change in performance?   I had been holding off on making the change because I have to have 2-D plotting for data checking and presentation.

Hey folks I am quite new to the software. I have a question of converting a nested matrix as in the attachment to a clean matrix. What I am doing is to manually match the row number to the final clean matrix. But since I will change the number of rows and the number of submatrix rows, is there anyway we can do it smarter? Thanks!

Standard 3D View component is good enough for me except two things: It`s impossible to pan and rotate view about some point (center of rotation) So, Is there some 3D view ActiveX component with panning and rotating about some point opportunities?

Hi, I have a problem with one element array in VBScript component. VB decide that it`s  TypeName is Double and VarType is 5 instead of Variant 8204 and CStr() gives "-1.#QNAN". So, I can`t get a value of my array. MC15 file is attached.

I need to find the X value for the following function where it breaks. Of course I can do it manually, but I would like to have a function, say Cr(D,u1,u2) that would give to me the x value where M(D,Gama,u1,u2) breaks.Can Anybody tell me how to do it? or Simply giving to me any function that does it?       Thanks in advance

Hello, Could anyone help me with fitting a Gaussian curve to the signals, please? In the attached worksheet, the function "plane1(k,x1,y1,d,taw)" detects the ultrasonic pressure filed amplitude on two microphones placed on the right and left side of the emitter. The peak of each signal is used to estimate the time of flight (TOF). For more accurate estimation of TOF, I use genfit to fit a Gaussian curve to the signals. However, the output of the fitting process (result(Data,taw)) does not look right and it sensitively depends on the scanned time range. In the current example, the signals time range do not exceed more than 0.01 s but the Gaussian fit works only when the time range is scanned up to 0.2 s. Is there something wrong?   Any suggestion would be highly appreciated, Payman

Hey I have problem whit mm^2,mm^3,mm^4 units it is not defined?
