How to create a 28x28 matrix in Mathcad

Have you tried assigning e.g. the last element in your stiffness matrix and then populate the other matrix elements? Something like this:

[pre] K[27,27:100 [/pre]

Now, you have a matrix with 100 assigned to the last element, the rest is zero. Now it's possible to populate the other elements like this:

[pre] K[row,col:value [/pre]

The graphical matrix definition is limited, but you can enter relatively gigantic matrices through an Excel component.

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

or, you can use the READ functions to read a standard text or Excel formatted file for a matrix
