M ATLAB array manipulation tips and tricks

Abstract

This document is intended to be a compilation of tips and tricks mainly related to efficient ways of manipulating arrays in MATLAB. Here, manipulating arrays includes replicating and rotating arrays or parts of arrays, inserting, extracting, replacing, permuting and shifting arrays or parts of arrays, generating combinations and permutations of elements, run-length encoding and decoding, arithmetic operations like multiplying and dividing arrays, calculating distance matrices and more. A few other issues related to writing fast MATLAB code are also covered.
