Basic operations in Octave/Matlab

A is a 1x5 matrix
A is a 2x3 matrix
2x4 2-D matrix
2x3x2 3-D matrix
A and B have same dimensions (2x3)
A and B have same dimensions(2x3)
(2x4)*(4*2) = 2x2 matrix
X is a 2x3 matrix of ones
X is a 3x2 matrix of zeros
eye(3) creates a 3x3 identity matrix and diag(X) gets diagonal elements from X

Accessing elements in a matrix:

X(row, column)
