    matlab accuracy problem

    No problems, I have managed to get it to work. I rewrote the code where it was placed into the matrix and there must have been something there matlab didn't like. All is fine now though. Thanks, J

    Many thanks for the help guys, M=dlmread('sample.dat'); sprintf('%04d\n',M(:,1)) allowed me to get my data in the form i needed, but I have found another way around it so it's formatted when I am checking the values. J

    Matlab Image Processing Help

    ok, so I can set the region of intensity that yellow lies between. Is there a function that can do this using RGB values? This is not for school, it is part of a research project for my Masters. The problem is simply my knowledge of Matlab and the functions built in.

    Matlab Image Processing Help

    It is not part of any homework, it is part of research I am doing and I am struggling to think of a way to do this efficiently since I do not know Matlab well enough. I am just trying to find functions with this capability or methods that would be able to do this.
