Matrices and arrays basics and fundamentals operations

I have a few matrices and arrays such as
Arrays : A = [1 3 5 ], B = [2 5 6], C = [ 1 5]
Matrices D = [ 1 3; 2 5], E = [ 1 3; 2 5; 1 4],
H = [ 1 3 4; 2 5 5; 1 4 6], I = [ 5 3 4; 2 1 5],

Please let me know which matrices or array can I multiply, invert, add?

Attachment:None


1. you can add or subtract 2 matrices or array, if both the matrices have same number or rows and same number of columns

2. you can multiply two matrices, if the number of columns of 1st matrix is equal to the number of the rows of the 2nd matrix

3. you can invert a matrix only if the determinant of a matrix is zero, and the number of rows equals number of columns.

Please watch the video for details..***********
