Cannot find an exact (case-sensitive) match for '~~'

I wrote the function, M-file. It makes a variable which save histogram of input arguments. And, I saved M-file at C:\Program Files\MATLAB\R2012a\bin

It is first part of m-file. function hist = ExHist( img )

so, In command window, I made a variable which saves image information. inImg = imread('~~~~~');

and, His = Exhist( inImg );

But, it occurs error.

Cannot find an exact (case-sensitive) match for 'Exhist'

The closest match is: ExHist in C:\Program Files\MATLAB\R2012a\bin\ExHist.m

I don't know how to do..

MATLAB uses the filename to call the function, not the name inside the function itself.

Use

His = ExHist(inImg);

It's best practice to name the function name inside the function match the filename, to avoid this confusion. (You probably have a little yellow warning inside the function, telling you that you violated that.)

Also, don't do this:

function hist = ExHist( img )

because hist is the name of a built in function. Don't destroy it by making it the name of your return variable - that's bad practice even though technically it's allowed.
