and a 2D matrix I1 of size 296X444.

I want to show of that portion of I where I1 have values 1; using the following code:

figure,imshow(I(I1==1))

it shows me the following problem:

Iout = I;
Iout(repmat(logical(I1),[1,1,3]))=0;
imshow(Iout)

corrected

Iout = I;
Iout(~repmat(logical(I1),[1,1,3]))=0;
imshow(Iout)

Thanks,It is correct but I dont understand the code bellow:

Iout(~repmat(logical(I1),[1,1,3]))=0;

what this line is doing?
