The function randisum() can draw random integers from a specified distribution, subject to user-specified sum and boundary constraints. Supported distributions are 'uniform', 'skew', 'exponential', and 'gaussian'.
Consider the simplistic example:
% Subdivide a vector into 10 randomly-sized blocks
x = 1:100;
blocksizes = randisum(5,numel(x),[1 10]);
xc = mat2cell(x,1,blocksizes);
I make no claims that these are particularly efficient, robust, or statistically meaningful ways to solve this problem.
