Does Mathcad Prime 7.0's Combo Box support units with exponents?  I am trying to enter steel properties in and when I type in^4 and in^3 that is exactly how it looks instead of in⁴ or in³.    

Hi, I am trying to find the local minimum of a function using Minimize function in Mathcad 15. I would like to use the Levenberg-Marquardt algorithm. However, I am unable to select this option from the menu, see the image below.  Please let me know if it is poosible with Minimize function.   Many thanks S  

I would like to convert my equations in a MathCad worksheet directly into a higher language (C or C++, or other) to run on a super computer.  Is there a software or second source software that can do this directly?

Hi,   First post here. i am trying to compute the following equation but unsure of what the error message is meaning and how to rectify. I have included the equation from the Eurocode in the screen shot.   Any help is much appreciated. 

I have matrix        A=    1   b            0  1   how can i use mathcad prime 5 to solve it for b?  

Hello everyone, The data points of a 3D surface are supplied in the accompanying worksheet. I'm looking for a slice of the surface at any azimuth angle. Through interpolation, I was able to extract the function that describes the surface. The function slice(phi) was subsequently constructed to slice the surface at any angle phi. Due to missing points on the original data on the rim, the interpolated function shows irrational behavior around the edges (except at zero and half-pi angle). In this example, the rim is a circle of diameter of 15.8.   What are your recommendations for dealing with this issue?   I am grateful for your aid.Best,Payman

@LucMeekes ....With your help from my previous post , I was able create a n excel table based on the timing matrix (both attached, plot the  waveform and then calculated average Power dissipation in a cycle... Can i do the same plot and find average  using range variable(from time vs power matrix), there by i can skip the excel part of it? Can you show me an example? Thank you Jacob

Help please!Prime 6 sheet in attach.

I have the below circuit for which the switch combinations S1,S2,Sx,Sy[0000...1111] gives me 16 combinations of Va voltages. I have 16 equations for the voltage values. From the equations I am trying to derive the Rc1, Rc2, Rc3 , Rc4 and Rbd transfer function. Please refer attached Mathcad sheet. The issue is, it takes forever to calculate the functions. What I could do to get the symbolic equations? EDIT : One thing I am thinking is to remove the node R2--Sy and then i'll have 8 combinations of Va. The Is and Va values are measurable quantities in my case, the switches and R1,R2 is my addition to the circuit with the intention to get individual transfer functions for Rc1..Rc4 and Rbd.

I am trying to find Transfer function for the variables Rc1, Rc2, Rc3 and Rc4 but the tool runs into runtime error . Basically, I need transfer function in terms of Rc1, Rc2,Rc3 and Rc4. EDIT : attached the worksheet. Now, I am getting out of memory as error.  

Relatively green Mathcad Prime 7 user here. I am trying to write a simple iteration program so that I can eventually try to adapt it for my needs. My question is: Why is my program returning 0 and 1 as well as multiplying everything by 1? I just want to see the values from 1..n where's f(n) is my input. I have minimal experience coding so I apologize if the answer is relatively easy or has been in front of my face the entire time. I will attach a file upload as well as a pictures, thanks in advance.

Thank's in advance

@Werner_E Can you show me the whole line that will be deleted from this file because I want to understand how it works.  

I have been working on this since last two days and just completed my work and then suddenly Mathcad crashes and gives me an error that the contents of the file have been corrupted.I tried everything, used the recovery file also but cant recover. I just dont know what to do.I would really appreciate if anyone can help me with this.ThanksP.S. the file is in attachment.

How to use genfit() to solve for nonlinear parameters since it is hard to separate I or V from the equation?

I am a new Mathcad user. I have a function defined for a scalar input. I have an input 4x6 matrix of scalars. I want an output of another 4x6 matrix of scalars, evaluating the function at each entry of the input matrix. That is:   Output(i,j) := function( Input(i,j) )   I quickly found that just entering the 4x6 input matrix into the function as an argument did not work. I ended up using two for loops to generate the matrix (i.e. evaluating the above equation at each i & j value).   My question is this - is there a single line command to input a non-symmetric matrix into a function for a scalar & get the output I want? Any other ideas or resources for how to do this?

Hello,   Mathcad Prime 7 n00b user here. I am trying to solve these two equations (pictured) by iteration without a previous value defined for Q but it is really stumping me. Currently I have Q defined but when it is undefined it really throws everything off and I am stuck. I will attach pictures and a file, feel free to edit as needed. Thanks!    

Hello,   I have a very complex differential equation that can only be solved numerically. Here I use a simple differential equation as a proxy for the sake of clarity. This differential equation contains the parameter a. I would like to determine this parameter a by fitting it with the method of least squares with my data X and Y. I need the numerical solution of the differential equation. From the numerical solution of the differential equation I only need the last value for each row of my data X. This is done by the function xsolvend. This is done by the function xsolvend. Because the differential equation is complex, I use genfit. For this I need the function xsolvend_fit which contains the derivative after the fitting parameter a. The numerical solution of the differential equation with determination of the final value works. See comparison with the analytical solution, which I can easily determine in this simple example. Already with xsolvend_fit there are problems and Mathca

Hello,Is it possible to link two mathcad sheets where one will be opened and the other is closed. The opened one will be set to a certain variable ( allowable stress design), and the closed one is set to a different variable( Strength Design). i need to import certain values from one sheet to another. the reason why i dont want to have one open becuase each sheet is about 25MB and if i have both opened along with other softwares, mathcad 15 will become extremly slow?Thanks!

  Hello,   I have data X and Y. I have set up 4 different models for these data. I would like to evaluate the significance of the models. You can see in the graph that model 2 (green) is the best. I want to achieve this result not by looking, but by using a correlation coefficient. My problem is that none of Mathcad's correlation coefficients give correct results. In Mathcad help, the Pearson correlation coefficient is often used for such purposes. From a workshop on Mathcad or from Wikipedia I know the general measure of determination. This provides plausible results. Only when the deviation is too large, as in model 1, does it deliver values greater than 1. Does anyone have an idea why this is the case? Thank you very much. Best regards Paul

Dear all, I have just install Mathcad prime 7.0.0.0 with a trial license. However, It seems that the program does not work as it always shows the error " Cannot understand this syntax" even the simple calculation like 1+1=. All other functions do not work as well, although the program has been activated successfully. Please let me know how to fix the issue. Thank you very much Best wishes,  

I am trying to solve this equation using iteration and a solve block for Q without previously defining Q as for my application I would not have the value for Q. Am I on the right track here and if not could somebody point out my mistakes? All of my other variables are previously defined and the only thing I don't have defined is Q. I want to be able to spit out a value for Q given all the other variables definitions. Thanks in advance! Below is an attachment of the solve block, I can provide SS for the other variables as needed.

Working on a large worksheet and the embedded Excel tables become unstable after being edited. Message: "Excel is busy: Can't activate Excel...". Which means the entire worksheet stops working. Need to close the file and reopen. This feature is very convenient and I wished it worked better.

I have one solution of this problem Great Comet of 1811 - Wikipedia But my solution is in XY-coordinares and a nee in polar coordinates. Help please See pictures and the Prime 6 sheet    

Hi Guys, So i have an equation that can't solve with with units (except in a solve block, which isnt optimal for me) if i strip the units the equation solves perfectly. I really hope some of you wise mathcad experts can help me.
