HelloI have issues with matrix calcualtions.  I am calculating the stifness matrix of something but I want to multipy a matrix by a vector. But I want to put unknown variable in the vector so the resulting vector is a function of the variable. I am ataching pictures to illustrate what  I mean. Thanks for any help.

Say, if I want to define the expression of Euler's formula below in Mathcad, how should I finish the input for that? 

Hello, I am reading values from an Excel sheet. I was building on the answer that Werner had for one of the questions. I have attached both P10 sheet and the excel sheet i am reading from. I was able to read the values for some but not others. The problem is there are dashes at TPP3,TPP5,...  Thanks,Sam  

The Mathcad Prime Documentation tab contains two dropdowns for adding and removing space, respectively.   The Add Space button allows the addition of a single line or a page.  The Remove Space button allows the deletion of a single line or all empty space down to the next region (if any).     I frequently add extra pages to allow plenty of leeway for adding new regions in between existing ones.  I always find it a bit of a nuisance having to press the Add/Remove buttons twice to tidy up the worksheet afterwards.   I don't think I've ever used the single line option for either adding or removing spaces.  It is almost trivially easy to carry out these tasks using the Enter or Delete/Backspace keys, switching to Draft Mode if necessary to ensure the correct cursor position (which is almost certainly necessary to use the single-line button options, anyway).   So, I was wondering if anybody makes use of the single line options, or would miss th

I'm trying to pull G number of rows from an array.  The For loop is not working.  It gives me the whole array instead.

Hi,How a Mathcad program will look like in which Barnsley fern  fractal plot can be seen?

I have a set of bounding temperature data Ti, at coordinates (xi,yi,zi).  I would like to linearly interpolate the temperature at interior points within the bounding points.  The bounding points could be like a cube, or other shape, or a plane or a line element.  Is there a mathcad prime program that can do this?

Hello, I have to process~750 rows, pulling values from another PRIME file using the INCLUDE statement.  I'm trying to write a text file in a certain format (just 6 row sample).  First column of values would have no quotation marks.  Second column of values would be text or string if a decimal place was included, only to two decimal places.  The delimiter between rows would be a comma.  Attached are a sample PRIME file of what I created and a text file of which I would like to see.Ideas?

When making a template in Mathcad Prime 10.0.0.0, i set the document -> View -> to "Draft".  I then save and reopen the template but it always reverts to "Page" view.  I never had this problem with Mathcad15.-Is there not an ability to set the user made template (document -> View) to always open in "Draft" on that specific template?-Additionally, i have the same question for setting the default zoom on the Document -> View.  Can the zoom setting be set in the user made prime template. Note: if i've got 10 people using the template, i doubt many of them will remember to manually change document to "Draft" view each time they open the template.   

Hello Community,I’m back after some time away from MathCAD due to other types of projects. This time, I need your expertise to help me resolve the following:I have several 3D zones defined by two opposite diagonal points, as shown in the figure below. I have prepared the zones as an m × 6 matrix, where each row is [x1 y1 z1 x2 y2 z2]. Row 0 → Zone 1, Row 1 → Zone 2, etc.I also prepared a list of points as an N × 3 matrix. Let PTS be N × 3 with columns [x y z]:My inVolume formula is producing the correct Boolean answer (1 or 0) depending on whether a point lies inside the volume or not. However, my matrix implementation is not producing the expected result. I would like also to work with units of length.    Attached is the MathCAD Prime 7 worksheet. You can reply in either MathCAD Prime 7 or 11.

I've been exploring various research papers and online resources regarding four-bar mechanisms, and I noticed that most of them include complex and advanced equations for motion and force analysis. However, my goal at this stage is to perform a basic four-bar linkage position analysis using Mathcad Prime 10. I'm dont often work  with mechanisms in Mathcad Prime, and I’d appreciate any help or references that can guide me in building a worksheet from scratch.If anyone can point me to beginner-friendly materials, share a worksheet, or walk me through the step-by-step setup, it would be incredibly helpful. Thanks in advance for your support! 

Hello All, I have attached P9 mathcad sheet. I am struggling to do four "if" statements. I have  four different exposures A,B,C, and D. I managed to do up to exposure B. I just did exposure "B" and I don't remember how i did it.I am not able to add another "else" statement for exposure C, D.  Thank you!Sam

When I am working I screensnip and paste sources I am using for my calculations on the side of the document for easy reference. If I try to copy them further down the same worksheet or into a different worksheet often the image doesn't paste and instead I get a "Browse for Image' button. THE IMAGE IS BEING COPIED FROM THE SAME WORKSHEET!! WHAT DO YOU MEAN??? It doesn't always happen, which makes it even more frustrating!! The problem is that the image is a screensnip and may have been taken by someone else using the document or not saved to my computer, so there is no file for which to browse.  I am kind of new to mathcad, so maybe there is something I am doing wrong, but this is a very aggravating problem to have.  Attached is an example of what I am talking about. Some of the images pasted, but not all of them.Also some screensnips.   Any help is appreciated!!

Hello, I defined an electron volt in terms of Joules, and tried to convert Joules to electron volts in prime 11, and got an error saying electron volt was undefined.   What am I doing wrong? I get the same error when I replace the J with the eV in the 2nd to last expression.  This worked in MathCAD 15. Thanks for the help, Paul

How to make the formula vertical alignment?I have some formulas like the picture below, how to make the formula vertical alignment in one vertical line?Now i use "Tab" key in keyboard, but it is not convenient.

HiI make a very simple sheat (mechanical problem), i don't understand why blocksolve  fail ?I can to solve it with my hand and paper.  For example , i find with my hand:FA = -8978613,01FS = -1038187,81FO = -9333161,37Can someone help me ?

Our Mathcad Community forum has an Ideas section. They don't let me in there for political reasons. Thank God they're still allowed in here.The best idea for Mathad is to take all the good things from SMath.I will post pictures here describing some of the benefits of SMath over Mathad.I ask those who have access to the Ideas section to transfer my drawings there.

This month we have another 3D geometry challenge. We are projecting squares onto cylinders and spheres and measuring the perimeter. Create a worksheet that calculates any of the following:   Challenge 1: Perimeter Calculate the perimeter of a square with a side length of 50 onto the following: A sphere of diameter 100. A cylinder of diameter 100 and length 100. Clarifications: Note that the square is projected from a plane that is parallel to a plane tangent to the sphere or cylinder. It is projected in a normal direction from the tangent plane as in the accompanying images. For the sphere, the square is centered on the point of tangency for the plane to the sphere. For the cylinder, the square is centered on the middle of the cylinder and the tangent point. If the intention is unclear, please refer to the images or post a comment where the community can help explain the scenario to you.     Challenge 2: Area Calculate the area of the above projected squares. &nbsp

Hello againI have (yet another) possibly trivial question.I want to make a program loop that will add elements to an array as long as the user wants to.Is this even possible in MathCAD?In python the basic loop would look something like below (formating difficult): answer='Y'counter=0array=[]while answer=='Y':    answer=str(input("Add another? (Y/n) :"))    answer=answer.upper()    array.append(answer)print(array) This can look like this when run in Python:Add another? (Y/n) : Y Add another? (Y/n) : Y Add another? (Y/n) : n['Y', 'Y', 'N']

Hi, I'm struggling with a function within a solve block that requires two inputs, a force and an angle as shown below So when I evaluate R3(F1a,_delta_) I get the error that it must be a 3 element vector. I'm pretty sure my mistake is simple, but I just can not work it out.  Any help will be greatly appreciated Shane 

I have a series of calculations that I've been doing in Prime 10 with no problem.  Now that it is opened in Prime 11, I get a plot error "These array elements must be scalar".  The plot still generates.It will not pass to a chart element and work.See attached document and data file.  Any ideas would be appreciated. Bob Adams 

I am getting error for programming could someone please help
