Dear all
I am attaching a file with a color transition that I want to use as the color palette for a imagesc plot. How can I do that?

% I don't have your image data, so I make
% a random matrix to use in imagesc()
data = rand(20,20);
% read colormap colors from the text file
cmap = readmatrix('colors.txt');
% create the imagesc plot
figure
imagesc(data)
colormap(cmap)
colorbar
