Mathcad

Hello,   Say I have a matrix called Y that is (21x21)  and I have matrix A that is (3x3). I would like to have matrix A placed in Y starting at Y1,1 so that  Y11=A11 Y12= A12 Y13=A13 Y21=A21 Y22=A22 Y23=A23 Y31=A31 Y32=A32 Y33=A33 I am new to using mathcad, thanks for the help.

I created delimited text file (XYData.dat) by means of python sentence '\t'.join(seq)+'\n' I`m trying to read delimited text file by means of READFILE command without success.   I can`t understand why tab symbols have different length (I discover this in Notepad+), may be this is the reason. And I can`t understand why MC separate commas in my strings (x,y,z becomes x y z). Data import wizard works good! Here attached two files for reference. Thanks in Advanced

HI, I am trying to find the T.s value in this file. Please  help me out. ThanksEnergy balance equation on surface of tube (Taking solar energy as source)

Sorry! I have published a blog and would like edit it. How can do it? https://community.ptc.com/t5/PTC-Mathcad-Blog/bg-p/PTCMathcadBlog

Hi,   This question is for Mathcad Prime 4.0. I have a sheet caluclating and plotting the true stress-strain of various materials. Now, I want to copy these values into a FEA software. To me, it looks like you cannot copy directly from variables and functions, so I figured I try to put in the data in an embedded excel sheet and copy from there. However, I ran into problems here as well.   I've figured out how to write the stress values (sigma_t) to excel. How can I write the values of the strain (epsilon_t) into column B?

What is the best way to find friction factor?

could you tell me mathcad prime and express comparation?

I am trying to use MathCAD to rearrange this equation to find e: but when I do symbolic solve it says no solution found. what am I doing wrong? If I do it as a solve block I can get a an answer for e, but I need to rewrite the equation so that I can put it in an excel sheet to do the calculations for furture use.  Thanks in advance for the help. 

Hi everyone, i have a problem when write a program about aeroelasticity   When i type "subscript letter" by press "." , Mathcad said the letter "A1, A2, A3, E1, E2, E3 "  : "this variable is undefined" But when i type it by "[", Mathcad said with "g(k)" : this array index is invalid for this array   Please tell me how can I fix the problem? Thanks all !

Hi everyone, I have a problem regarding the time it takes for my computer to plot all the graphs and do the calculations in the attached file (it takes around 15-20 minutes). My question is, is there a way to optimize the calculations or do I just need to buy a more powerful laptop?P.S. I use Mathcad Prime 3.1 

Good day to everybody. Can anybody help me with an example of bilinear interpolation in mathcad prime please?

Hello all first of thank you all for being quick to answer my questions since I'm a mathcad newbie. But to the question is there a way to place a variable in a text string so when the variable changes the text changes too?

The only way I know to get a numerical answer is to add an = sign at the end of my symbolic evaluation started by -->. Is there any way to skip that step and have Mathcad directly solve my problem numerically? I'm doing some nasty integrals right now and I don't need it to solve it symbolically if it will take forever.   Thanks!

Hello,   I'm looking to reduce a dataset of 25 points to a surface curve fit.  An older program (and required to be used) generated the points in question.  Rather than spending many more hours on input the values, I was hoping to get a curve fit to the equations.  Two variables of distance (x) and elevation (y) provide and output of heatflux (Q).  I'm looking to essentially extrapolate the data into a large portion of points that will undergo more transformations pending the target geometry.   However, I'm unsure how to appropriately reduce the data.  There isn't any issue with generating a x^3 curve for more than 3 points of data (as I've done before), but I'm seeming to be inputing something incorrect into MathCAD for trying to reduce the data to an appropriate approximation.   In addition, if somebody knows a way to accomplish this task in excel, that would also be benificial (though I question if excel has that power built into it). &nb

Hi Everyone!I've been using Mathcad for a while and I believe it is a powerful tool. But in the last week I've been experiencing a problem. I need to create a dynamic link between Excel and Mathcad as the raw data I am working with is too much to be just copied or imported. There is a constant 'flow' of new information going straight into the excel file and I need it to be linked directly to Mathcad. (as we are talking here about thousands of results).Will be very grateful if you can help me out! Thank you very much in advance!Kate

I'm trying to find the work done to compress a gas by integrating a pressure-volume graph in terms of the crank angle of a piston. When using the integral function in Mathcad, an error comes up saying that these units are not comparable for p(theta).  Any help would be appreciated.

Hi!  I have a license for Mathcad 3.0. It is an educational license, and was acticated 2,5 years ago. Now I have bought a new computer, and should like to transfer the license to this.   Somehow I cant find any sufficient information on how to do this in earlier posts, and would be very grateful for any help!   It should be mentioned that the license is currently running on a Macbook through Parallels Desktop, and will be transferred to a Windows 10 Lenovo laptop.   Kind regards,  Morten from Denmark

Hello, everyone.    I'm trying to create a MathCad sheet to dimensionate RC Columns submitted to Combined Bending and Compression, but I'm having trouble finding materials about this in the internet, mostly MathCad stuff. I was wondering if anyone has a sheet that calculates this or something similar to this, that could be sent to me.   Thanks in advance,   Daniel

This is a short worksheet that I need solving. It's easier to learn when I can see the solutions already. Please anyone help.

I posted a thread on here just a couple minutes ago, but it was rejected in the moderation stage:   https://community.ptc.com/t5/PTC-Mathcad-Questions/Can-t-get-Mathcad15-to-accept-Prime4-license-but-support-wnats/m-p/485315   Why was it rejected? Please don't reject my posts like that. I'm not a spammer, so you don't have to block my posts.

2 weeks ago, Mathcad Prime 3.1 wouldn't start, the logo blinked and nothing happend... I uninstalled at removed every trace of the program, re-installed and tries countless times to do this.. nothing worked.. I got so pissed that I formatted the whole PC! finally.. Mathcad worked again.. for 4 **bleep**ing days! yet again this **bleep**ty supported and made program is failing, without reason!

This is the displayed message:The file type is not supported. Log file is located at C:\ProgramData\PTEc\MathcadPrime\Logs\MathcadPrime_Exception_20170610_125046.log

How do I download and install Mathcad 15 M030?I have Mathcad 15.0 (15.0.0.436 [006041742]).Thank you.-Jeff

Hello PTC Community, I just removed Mathcad Prime 3.1 to install the 4. version. But in during the installation process, the installation fails at just 1%. What is the reason for this?

Can anyone help me figure out what I'm doing wrong? I can't seem to get a plot that shows, Eavg on the y-axis and Eavg(C1) on the x-axis...
