Mathcad

Hello,   I want to assign a number in "d" from "b" in the following way. Firstly, I will input any number in "c". Secondly, I want to acquire the index number from "a" such that the value of "a" matches with the value of "c". Thirdly, Then with that, I will assign a value from "b" to "d". I can do the first and third part but cannot do the second part. It will really be helpful if you please help me out.   Faisal  

Can you help about this error  

HiI have been plagued with a problem with Mathcad 15.0 (M030 [MC15_M030_20131216]) in which randomly I receive an error that says "Server busy.." When I click on "Switch to" it opens start menu. If I click on "Retry" it gives the same error.I have tried searching online/this forums but I couldn't find a solution. Does anyone have any remedy for this? If not then I have to regrettably move on (or back) to Mathcad Prime 3 ThanksOmkar.

Hi, I have used the polyfitc regression function to fit a polynomial to a set of data. The curve describes the deflection of a beam, and so must be zero at specific points, x (the supports). Unfortunately, the roots are slightly inaccurate. Is it possible to force the roots of the output of polynomial regression function?   Many thanks and kind regards

There is an utility that allows you to save Mathcad Prime files in older versions Mathcad. See the picture below and the instructions here

Hello,   I'm finishing my master thesis and to get the results I have to make a new version of my advisor's old work, but I'm getting a lot of erros, someone can help me to fix? in annex are two files, one in word and one in mcdx.   PLEASE I'M ALMOST LOSING MY CHANCE.

cant open the file this morning. hope some one can help me. need to be done by the  05-04 and just cant open it  and its all done .. help 

Good morning, I'm trying to create a mathcad code for analysis of RC sections but I'm getting this problem. It was supposed that the vector esk was 10e-5 in all elements, but some in some terms I'm getting 4x1 when was supposed to be 0, how can i solve it? My code is in annex if someone wants.

I believe the last time I tried converting a Mathcad 15 file to Prime was with Prime 3.0, and as I recall it was a dismal failure.  I use Mathcad to solve sets of simultaneous nonlinear equations, with lots of 2D and 3D plots to visualize the output. It is very easy in Mathcad 15, and I am concerned with PTC's inability to recreate Mathcad 15's plotting capabilities in Prime. I thought I had read something to the effect that PTC was not going to support Mathcad 15 after Windows 10.  Can anyone tell me if this is true?  If so, I may have to search for a new tool.

I am somewhat new to fitting data using Mathcad (15), so I apologise if this is a stupid question.   I have experimental data on the temperature dependence of the molar volume (Vm) and isochoric specific heat (Cv) of a compound.The former is related to the internal energy, the latter to the first derivative of the internal energy. If I use Debye-based models, then the Debye temperature is a common variable for both functions, the molar volume includes two additional variables. The number of data points for the two independent data sets is different. I can fit each function separately, but I wish to fit them simultaneousy to determine the best estimate of the Debye temperature.   Is there a simple way of carrying out multiple function fitting in Mathcad?   Many thanks   Kevin

Hello,   I am trying to make a program using Mathcad. My goal is to first finish calculation for a column of data, assign the outcome and then progress to the subsequent columns. The program is telling me that "Array Index is Invalid". Please help me out through it. My version is Prime 4.   Thank you, Shakib

In the thread Re: Similar to vector matrix product, but different… the poster put the return value from a program inside the loop, which you don't normally see. Out of idle curiosity, I wondered if it had any effect on Mathcad's performance by doing this rather than placing the return value outside of the loop.   I also wondered what effect using the Prime row operator would make and doing without the vectorized multiplication.  What I found rather surprised me, in that the row operator method was considerably faster than the original column method.   I looked at doing array expansion by replicating a column-wise to conform with b and then doing Hademard (element-by-element) multiplication.   I also tried transposing b, multiplying each "column" by its corresponding vector element and then transposing the result.  This is what I found (on an i7 with 8 GiB RAM running Windows 10).I was surprised to see that the row operator method was so quick.&nb

Hi everyone,   I am experiencing two problems:   1. The classic "this value must be a matrix of scalar elements" when trying to multiply matrices. I have multiplied matrices which had complex elements before, so I am unsure why now the elements must be scalar.   2. Every matrix element below shows as {1,1}. How to show the actual values of each element instead?   Thank you.

Can someone please advise on how to rectify the error in attache sheet?

Hello.I've been trying solve 5x5 matrix for some time method of newton but something is not correct. Anybody can help?

I tried to look up soil layer properties based on layer depth shown in the table using function Shaft_Matrix. Don't know why the Shaft_Matrix function returns layer 2 properties at depth 5'. I have been stuck with this for a while, still cannot figure it out. I would really appreciate if anybody can help. Thanks 

Can I populate a table from a group of vectors? If so how?

i am trying to program ;this routine (that i picked up from another topic here, originally written in mathcad 15) to calculate the depth to the midpoint of each layer.  the results for z should be 4.5, 13.5, 22.5, 31.5, 40.5.   any assistance would be appreciated.  the file is in mathcad 4.0

what is this?? could anybody tell me? i just want the simple answer..  

Hi guys.   I have a problem and I don't manage to solve the equation by myself. Can you look into it and say what is wrong?   Thank you.   P.s. It's the last equation.

Hi   I'm unable to graph   the data. It says t is not defined but   it is a function of t Please help

Hi,   does anybody know a way, apart from using another data set, to have a marker in prime's chart tool?   Raiko   P.S. btw. awful tool

Hello,   i have a problem with mathcad (Mathcad Prime 3.1): No solution was found, try changing the guess value or the value of TOL or CTOL Can please somebody check it out, and tell me what i need to fix?   Thanks!

i am sure the answer is obvious, but at the moment i am not seeing it.  how do add the "otherwise" statement or function?  i have read that you have to click on the function button and not just type the word.  but i do not seem to be able to find the required button.
