Hello to all
I have a matrix called A, which contains some
numbers. I want to add the symbol s to some of the elements of the matrix and
then take the inverse laplace transform of the matrix. but I can't do it. It
gives the error below:
??? Undefined function or variable
's'.
Error in ==>
D:\MATLAB\toolbox\symbolic\@sym\double.m
On line 45 ==> D = reshape(eval(X),m,n); Error in ==> D:\MATLAB\work\circuit.m
On line 124 ==> if m~=0, y(m,m)=y(m,m)+s*element_value,end The code I use is:
syms s
if m~=0
y(m,m)=y(m,m)+s*element_value;
end
in which "element_value" and "m" are scalars
defined beforehand.
I would appreciate it if somebody helps
me.
Regards,
Zeinab Ghofrani
