Hey everybody, I try to find an alternative to im2bw(x,y).
Here's the code excerpt:
A1 = imread('filename.png'); A2 = im2bw(A1,0.5); %Make BW matrix (0=black, 1=white)
thanks for helping

Lisa - are you looking for an alternative because you don't have access to this function? I don't think it would be that difficult to come up with your own implementation of this function.

If you do not have access to the Image Processing Toolbox as Geoff commented, you can manually threshold, as described in the following post:

To threshold at a level of one half, try this:
level = intmax(class(A1)) / 2;
BW = A1 > level; % Or can use < instead to get dark things.
