This is a practice for a classwork.

In this approach the colors in the image are determined by a colormap. The values stored in the image matrix are scaled, and the values are correlated with a known map. This approach works well when the parameter being displayed does not correlate with an actual color.

map = colormap;

[r c] = size(map)

cmap = reshape(1:r, 8 ,8)

image(cmap)

Write a script that will generate a 50 X 50 image of pixels. The lower triangular part (including the diagonal) will be all yellow. The upper triangular part will be randomly either red or green for each element.
