I've only relatively recently acquired recent-enough release to have accumarray(). Despite my efforts the documentation for it seems to remain totally opaque to me.
a) Anybody know of any more detailed tutorial/description than that of the online doc's? Mayhaps the old dog could eventually learn the new trick w/ another bone to chase, and
b) I was trying to build an index array of the vector 1:k, w/ each row 1:n being one greater than that in the preceding row. I brute-forced it w/ repmat() and cumsum() but seems like accumarray ought to be the tool. But, all my efforts were totally unsuccessful (and for the most part I couldn't even precisely decipher why got what did get)...
