how to assemble a symbolic matrix?

Hi, so I have to assemble a stiffness matrix with symbolic variables. If I give the variables numbers, the code works but if I try to let it run with the symbolic variables it says sym not convertable to double. Can anyone think of a solution?

Ke is a 10x10 matrix and is assembled by multiple 6x6 matrices so I first set Ke as a matrix of zeros, and then let it be assembled via a loop

Hi Clara,

Can you please share the code which you are implementing?

Why would you be using symbolic variables? A stiffness matrix is something used in numerical methods for partial differential equations.

I have the problem fixed, i just needed to add a 'sym' in my Ke matrix thank you all for trying to help
