MATLAB program and files always have filenames ending with
'filename.m'.
Some of the basic matrix commands used in image processing are as
follows:

To display a matrix
a = [1 3; 2 4]
b = a*a (element by element multiplication)
b = [1 9; 4 16]
Addition of two matrices - a + b
Inverse of a matrix - inv(a)
zeros (1, 3)
ones (1, 3)

Some of the MATLAB commands used in image processing are as follows:

1. Reading an image A.
X = imread(A)
2. Displaying an image
imshow(A)
