resize each pixel in an image based on its width and height

I want to 2d plot something like the picture but I don't want to use pcolor since it plot the center of every two pixels i.e., if my Matrix A has the size of (10,7), the pocolor gives (9,6) pixels. Imagesc doesn't have this problem but I cannot adjust the pixel size like what pcolor does (image below is with pcolor). Do you have any suggestion for this problem? Thanks

Use texture mapping onto an irregular grid.

Thanks.I looked into that and still reading. I'll get back it that works and doesn't reduce the number of pixels in x and y direction. But I think it is the "surf" function that does the same thing as pcolor.

No, texture mapping does reduces the pixels by one in each direction.
