I currently have a 30x30 array with intensity values. I can plot this with colour intensity on a 30x30 grid using imagesc.
I also have a 30x30 cell array where each cell contains the x and y dimensions of the corresponding intensity value.
I want to create a colour intensity plot but to define the size of each 'square' using the cell array.
Is this possible?

You'd have to loop over all cells and stitch them on one at a time, possibly enlarging the existing matrix before stitching. Of course if adjacent blocks have different sizes, then some "background" must show "underneath" the smaller one.

Thanks -
So I should loop over the cells and I guess assign each cell a start and end value for both x and y directions?
Then how do I plot it? imagesc wont work will it?

Just loop and stitch. Here's how to stitch
tallImage = [image1; image2];
wideImage = [image1, image2];
Just build it up horizontal bands first, then loop and stitch all the horizontal bands together.
You can use imshow() to "display" it, not "plot" it.
