This function searches for a pattern in an array

This function searches for an n-dimentional pattern in a k-dimentional array.

Its output is the linear indices of the beginnings of matches. Matches can overlap.

There are 2 debug blocks: the first is for generation of a random array & pattern, and the second is for output check using subscripts and ranges.

I tested the function on random 0-9-dimentional arrays and patterns, and on arrays which were repmats of patterns (to compare performance when there are a lot of matches with performance when there aren't).

• Note that NaN's are not equal to each other, and will not match.

Much thanks goes to whoever wrote ind2sub, as I took some ideas from it for the n-dimentional loop.
