Hello everyone,
I am using the symbolic toolbox to create symbolic matrices, then I need to evaluate the value of each members of the matrix.
So, here is what I have done so far.
clear;clc;A = sym('A', [2, 3], 'real')for i = 1:2 for j = 1:3 A(i, j) = i*j; z = str2sym ( strcat('A', num2str(i), '_', num2str(j) ) ) endend
Then, I obtain:
>> A A = [ 1, 2, 3][ 2, 4, 6]
However, when I want to get the member value, e.g: A1_3, I got the error "Unrecognized function or variable 'A1_3'."
That's why I created a string and conver to a symbolic value, and store in z. But I don't know how to get my Ai_j = A(i, j).
My goal is that each member Ai_j of the symbolic matrix gets the value of A(i, j). Can anyone help me with this ?
Thanks in advance.
