MATLAB Pull Value from MATLab Matrix: Solve the Problem

[Ethers0n]

Does anyone know how to pull the value of an element which has been calculated and placed in a matrix out of the matrix?

ie.

M = [a1, a2;
b1, b2];

c = a1*3;

?

I can't seem to find any information online...

Thanks.

You reference elements like this:

Given any matrix

M=[a1,a2,a3,...,an;
         .
         .
         .
   m1,m2,m3,...,mn]

an element is accessed by referenceing its row and column position. So,
M(c,10) would return the element loacted in the third row, 10th column.
