显示 更早的评论
this is the code:
clear all
load('BrainTumors.mat');
imagesc(MRI{1});
colormap('gray')
a = mat2gray(MRI{1});
the last row isnt running and thats the error:
"Undefined function 'mat2gray' for input arguments of type 'int16'.
Error in ExecriseSolution1 (line 5)"

Do you have access to the Image Processing Toolbox for the license you are using to run this code?

The mat2gray function is part of Image Processing Toolbox. Do you have this toolbox installed and licensed? You can check this by running the ver command and looking for a line starting with "Image Processing Toolbox" in the displayed output.
If that line does not exist you will need to install Image Processing Toolbox to use this function.

If you have a recent matlab I suggest substituting rescale()
