How to change variable into number in matrix, for example I have A=[a b c]: Then i declare a = 1 b = 2 c = 3 So matrix will be A = [1 2 3]
Thank you

Why are you originally defining A as A = [a b c]? This isn't very common or efficient matlab usage. I would suggest starting with A = [1 2 3] and adjusting the values as needed. As for the change, see below.
% Defining A
A = [1 2 3];
% Changing A to 2 4 6
A = [2 4 6];
% or
A(1) = 2;
A(2) = 4;
A(3) = 6;

Like this?
a = 1;
b = 2;
c = 3;
A = [a b c]
