Answer 2

>> edit imnoise

[John D'Errico]

Admitttedly, I tend to avoid edits, especially by novice users. Too dangerous that they will modify the code by accident. But edit will of course work.

[Sean de Wolski]

UAC usually prevents authoring these unless MATLAB is run in admin mode.

I personally need the color highlighting to discern what's going on.

Sean de Wolski :- do u know the code behind the function imnoise(I,'salt & pepper',0.02);????? plzz help

[Sean de Wolski]

Yes, I can see it by reading the file that opens when I run the above command.

Answer 3

[John D'Errico]

I don't have the image processing toolbox, so I cannot know which is the case, but the answer is still clear.

If imnoise is not a built-in function, then it will be an m-file. If it is an m-file, just do this at the command line:

type imnoise

If imnoise is compiled code, then there is nothing that you can do to see the code, except perhaps to get a job at the MathWorks.
