[rows columns numberOfColorChannels] = size(yourImageArray); % Best way
For images, make sure you use the third output argument. Otherwise if it's a color image and you do
[rows columns] = size(yourImageArray); % unsafe way to do it.
then your columns will actually be columns multiplied by the number of color channels (3) in your image.

@Esther: It is not surprising that the command size determines the size of arrays. I recommend to read the "Getting Started" chapters of the documentation to learn at first the basics and at second how to find related information in the docs.

first store your array in a particular name for ex A= 1 2 3 4 5 6 7 8 9
then [m,n] = size(A)
shown the size of your array
