One simple option would be to make a heatmap using imagesc: active = [0 0 0; 1 0 0; 0 0 0]; imagesc(active) axis square

Tengo esta figura, y deseo sombrear la región entre la linea amarrilla y la linea roja. Tal vez alguien pueda darme una idea de como hacerlo. Muchas gracias :)

Both the patch and fill functions are useful for doing this. See examples in the documentation.

Assign a line in every element of a 3d matrix

To replace all values of 10 with 101.543, you can do val(val==10) = 101.543; Maybe that helps?
