MATLAB: How to Plot a Matrix

Question

Hello everyone,

I have a 31*31 matrix. Each element of this matrix has a value between 0 and 1.

I am trying to plot this matrix so that one axis of the graph shows the number of columns and the other one shows number of rows (This will make a grid with 31*31 squares). Now i want each of these squares to have a different color according to the value of the corresponding element in the matrix.

Can anyone help me with this please?

Thanks in advance.

PS: Final result will be something similar to this:

(In my case it will be 31*31 squares instead of 14*14 squares)
