Hi MathCAD Community,To start I will try and give some background to the problem:I have imported some data points that represent two edge curves of a surface in Creo. Using Matricies I can rotate these data points by a given angle made up of Yaw and Pitch. I then project these rotated data points to the zero plane using a projection Matrix. Next I fit a function through the two sets of transformed data and using integrals I calculate the area between these curves.Now that I have worked out how to do this by specifying the rotation angle I want to iterate through 180 degrees of rotation in Yaw and Pitch to find the orientation that provides the smallest area between the curves.My problem is when I go to find the potential intersection points of the two curves (for defining integral limits) I use a solve block, which cannot be implemented within a for loop for iterating through angles...If anyone could help me find a solution to this ASAP it would be greatly appreciated. I have attached

Hello, I need help with settings Mathcad Prime 3.1. How I can improve visibility grid of the worksheet?I can change the background color of the worksheet?

Hi,Recently I finished my project in mathcad 15 but for the perpuse  of print editing, I need to copy text and equations to word. I dont have any problem with text but when i copy equation the result of equation is gone:If I double click on the equation in word the extra mathcad window will open. Thanks to that I will get the result of equation but  font will be changed permanently: I am able to copy equations as a photo but then spaces beetwen lines are messed up.So what can i do to copy equations with result and to keep the same font?

Hi, everyoneHere I am trying to find the eigenvectors of C using the function eigenvecs,I know eigenvecs returns to all the eigenvectors of C, My hand calculation shows the two eigenvectors corresponding to the two eigenvalues should be[0.39;1] and [-0.64;1],So what does [1.56;1] and [-2.56;1] represent?Thank you very much!Shawn

To community:The attached worksheet shows two programs.The one on the left shows one way of repeating a calculation that works and accomplishes what it is supposed to do.The one on the right is an attempt to0 do the same by iterating the calculations but only goes into a recursive mode.Would like help in the proper programming procedure.Thanks for any helpDick.......Iterative Programming.xmcd.zip (31.6 K)Download

Would someone be so kind to print the document "Easy Fit" of the latest blog into pdf format? Thank in advance!

I'm a MathCAD 15 user. Does MathCAD have logical indexing function? In other words I want to find the indices in a matrix where the values of the matrix are within some criteria. For instance I would like to find the row and column numbers in the matrix below that are between -3.8 < G(i,j) < 2.3? Sure I could write a small function to do this but if I were using Matlab A=G(G<2.3 & G>-3.8) would get me what I need.

how do i calculate the coefficients using the polynomial coefficients under the symbolics toolbar.

Hello... Some time ago there was a study on Pro Mechanica to the buckling of a Soda Can.It seems to me also on MathCad.A person would still have these files or link to retrieve.Kind regards.Denis

Hi all,I have been struggling to solve a  nonlinear equation, no matter what guess values  I use it seems Mathcad just won't solve it. Please see attached file.I just need to find the values of P0 at t=0,0.5..5 seconds.Thanks very much,

HiTrying to complete simple question on motors but can not get the formals to work in correct unitI can not get Nr be 600 rpmAngular Velocity to rad/sThis basic unit error the follow down document toRated output power kWand finally motor Full-load efficiency in percentage %Can anyone help, see attached fileThank in advance

Looking to see if anyone has defined an impulse load such as psi-ms?

I've followed the directions on the Author's Reference, yet when executing the Ebook *.hbk, I get blanks.  What am I missing?  The Reference is not apparently seeing the type of input through the MCAD engine?  ZF

Hi All,All my files had been made using Mathcad 3.1 but at the moment I need to open them on a machine which has  Mathcad 3.0 installed and it doesn't have the option of the converter application. can anyone please help me to resolve this?thank you 

Dear All,I would like to receive clarifications about the solution of a nonlinear system through the use of a solve block Given/Find. In the attachment it is reported the  system that make use of the symbolic derivative operators ( EOS isothermal inflection point- critical conditions ) . The solution converges only up to a certain value of the input parameter ( epsaa, Vaa ).  Any suggestion how to solve this issue?Your sincerely,Massimiliano

Hi, everyone,Is there a way to find the value of lambda using the eigenvals function in Mathcad?What have I done wrong such that it cannot return to the numerical solution such as the polyroots results?For this simple question, the polyroots function is acceptable,but I assume using the eigenvals be more convenience when there are much bigger matrix that needs programming. BTW, is there any recommendations for the method to use, when say there is a N Degree of Freedom vibration system, that N is the input of a function, that returns to the eigenvalues and eigenvectors. Is the built in Eigenvals function convenient to use?Thank you!Shawn

Hi,I am calculating COG of a stack of 9 elements. I want to create a 9x1 matrix where the first row contains cog of all element above element 1, row 2 contains cog of all elements above element 2 - and so on. I have solved this by making a 9x1 matrix and putting in the cog formula in every single cell. I do not like this because it takes up so much space and it looks quite bad. Is there a way of telling Mathcad that "i" should increase by 1 in each row such that my expression can be expressed in 1 line? Or is there another neater way of achieving the same goal?Another thing could be that Mathcad will only show row 1 to 9, and that the other ones will be visible when I edit that matrix, but I can't find an option for that either.

Hi!I am trying to solve for a simple wave equation using the Pdesolve function. However, it returns an error saying "This variable is undefined". I made sure to follow the proper format. Can you please help me locate where I went wrong?Thank you!
