How to create a 28x28 matrix in Mathcad

How to create a 28x28 matrix in Mathcad

How to create a 28x28 matrix in Mathcad

(OP)
Hi, I am trying to calculate a stiffness matrix of the size of 28x28. However there is a limit to the size of a matrix in mathcad of 600 units. Is there a way of getting around this? or an alternative method I can use?

RE: 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:

 K[27,27:100

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:

 K[row,col:value
