MATLAB: Plot a 100×100 grid of 1’s and 0’s

gridMATLABmatrixplotting

I have a 100×100 matrix of 1's and 0's that form a grid pattern with diagonal lines through it. How do I plot this on a graph for a visual representation of the pattern?
example:
1 1 1 1 1
1 0 0 1 1
1 0 1 0 1
1 1 0 0 1
1 1 1 1 1

Best Answer

See imagesc() or heatmap() or image().
The axes will not be 'on' for imagesc or image but you should turn the axes on so you can see how the axes are arranged (particularly the y-axis). 
axis on
If you plan on customizing the plot, heatmap is more difficult to work with.
