crop arrays with axis-aligned minimum bounding box

| Watch this File

File Information
Description

Often I have to extract a subset of a two-dimensional array for further analysis. Usually I do this with logical indexing. But most often the problem with logical indexing is that I get a column vector which I then have to reshape or index into a new array.

cropmat solves this problem. The function crops a subset of an array based on the axis-aligned minimum bounding rectangle. One advantage is that you can perform the operation on several matrices (e.g. coordinate matrices generated by meshgrid) at one time. Moreover, cropmat works on arrays with an arbitrary number of dimensions.

MATLAB release MATLAB 7.8 (R2009a)
Other requirements The example in the m-file requires the Image Processing Toolbox.
