This comes following Michael Croucher’s post MATLAB: Repeated multiplication is faster than integer powers. He noticed that in MATLAB doing element-wise exponentiation of matrices (using .^ operator) was slower than explicitly (element-wisely) multiplying the matrix by itself. I’m pretty sure this is only true for small exponents, anyway. He also wondered how was it in other […]

I’ve developed a Julia package to manipulate symbolic linear expressions with both scalar and matrix coefficients: I created it mainly to manipulate large linear matrix inequalities (LMI) for SDP optimization, and I’ve been using it whenever PyLMI-SDP is too slow for the job.
