During my practice i notice the few lines, related to "colormap" function.
load flujet
image(X)
colormap(jet)
How can i read and edit the 'flujet'.

flujet looks to me to just be a .mat file. It should just be data (an image) and is being loaded in the MATLAB workspace as the variable, X.
If you enter
>> whos X
you will see information about X, its dimension and data type.

You can also do
whos -file flujet
to see what is stored inside the file flujet.mat

Then you should rephrase your Question. Initially, you said you wanted to read/edit flujet.mat. This is obviously unrelated to the code that created flujet.
Aside from that, I don't know how you hope that flujet will carry information about its creator. If I give you an mp3 music file, do you expect it to carry the software that created that mp3 file?

The file "flujet.mat" does not contain information about its creator - usually. You can inspect the contents:
Data = load('flujet')
Now Data contains all variables. Perhaps, if you are lucky, the creating program added a variable like
Data.Creator = 'mips.m, version 1.8, written by Thomas.Moore@Belgium.com'
But this is not very likely.
