How to create a color map from a [0,1] matrix setting color range in [0,1] interval in Matlab

Question

Consider a matrix whose values are all in the real interval [0,1]. I am trying to get a color map from this matrix in Matlab.

My problem concerns using both the image function or the HeatMap object in the Bioinformatics toolbox. However what I really care about is the color range.

How to specify it?

Most important thing: how to specify that the minimum heat color and the max one must be reset to interval [0,1]?

Answer 1

You can use imagesc to specify the color range.

 imagesc(rand(10,10),[0 1]);
