When calling in main function then this error occurs.

Answer 2

[madhan ravi]

im = rand(1,10)
F=feature1(im) %calling of function

function F=feature1(im)
im=double(im);
m=mean(mean(im));
s=std(std(im));
F=[m s];
end

[madhan ravi]

Please note that feature is an inbuilt function of matlab so i changes it to feature1 in case to avoid shadowing.

[madhan ravi]

So use imread to read Image file

[madhan ravi]

I told you to change feature to feature1 did you even read my comment??
