This FEX submission provides some functions that are similar to MATLAB's usual findgroups() and splitapply() commands, except that they are specifically well-suited to scenarios where the groups are subsets of consecutively repeating elements in a vector.
EXAMPLE: To find the run lengths of consecutive non-zero elements in,
>> X=[0 0 4 7 6 1 3 0 0 0 1 11 3 8 0 0 47 14];
one can simply do,
>> runlengths = groupFcn(@length, X, groupTrue(X>0) )
runlengths =
5 4 2
