i have been working on this code
syms k
K = zeros(8);
K(1,1) = 0.7499*k
MATLAB shows the error "unable to convert expression into double array"
Also in general How do I create a matrix with symbolic expressions as element values for any given matrix.

Hi Parth,
Do not define the K with double variables and that should help. Instead directly create the matrix with those many symbolic variables.
Hope this helps.
Regards,
Sriram

Make K a sym array from the start. Then MATLAB doesn't need to convert the symbolic expression 0.7499*k when assigning into an element of K.
K = sym(zeros(8));
