imread can read your image file as a matrix.

Have a look at this question.

Basically, start with the imread function, and take it from there.

As soon as you've loaded the image into Matlab, it is represented as a matrix. For example

>> A = imread('peppers.png');
>> size(A)
ans =
   384   512     3

A is a 384-by-512-by-3 array, representing an RGB image, where e.g. A(:,:,1) is the red channel
