how to call a function with multiple output argumnts

how to call this function

function [RHist,GHist,BHist]= RGBHistInter(imData);

RHist = [];

GHist = [];

BHist = [];

%extract Red

[Rcounts,x] = imhist(imData(:,:,1),16);

Rtotalpixels = sum(Rcounts);

for j = 1:size(x)

RHist = [RHist Rcounts(j)/Rtotalpixels];

end

%extract Green

[Gcounts,x] = imhist(imData(:,:,2),16);

Gtotalpixels = sum(Gcounts);

for j = 1:size(x)

GHist = [GHist Gcounts(j)/Gtotalpixels];

end

%extract Blue

[Bcounts,x] = imhist(imData(:,:,3),16);

Btotalpixels = sum(Bcounts);

for j = 1:size(x)

BHist = [BHist Bcounts(j)/Btotalpixels];

end

end

From the command line:

 [RHist,GHist,BHist]= RGBHistInter(imData);

You just have to save the function RGBHistInter.m in a folder on the MATLAB path. Or, better yet, save it in a folder that you add to the MATLAB path with

 >>addpath 'c:\thisisthepath'

or using

 >>pathtool

For example, suppose you have a folder called c:\mfiles

>>addpath 'c:\mfiles'

Save the function .m file in that folder and then if you enter

>>which RGBHistInter

you'll see that MATLAB recognizes the function.
