Comments:

Various manipulations with matrices.

The examples above, illustrate the case where a larger matrix can be created

from smaller ones. Also, pay attention that Matlab returns an error if the

user tries to combine row or column vectors with different lengths to create

a two dimensional array.

Usually, it is imperative need to store the size of a matrix in some variables.

This can be done via a build in function named as

Matlab’s command:

>> [m1 n1]=size(A1); [m2 n2]=size(A2); [m3 n3]=size(A3);

>> M_N=[m1 n1; m2 n2; m3 n3]

Matlab’s response:

M_N =

2 5

4 5

2 7

Comments:

Using the

e function to find the size of various matrices. Each

row of the

N matrix contains the size of matrices

2 and

3 respectively.

2.2.1 Transpose of a Matrix

Recall matrix “A” that was defined earlier. The transpose of “A”, symbolized

in linear algebra as “A

” is the following:
