Hi, when creating new functions in Julia, do I need to specify the input type of the arguments ? Is this required for speed or only for organization ?

No, this is not required.

Multiplication times for complex matrices: julia vs Matlab

I’ve been looking at some different filter approaches for analyzing ECG signals using Matlab and have recently implemented them in julia in order to get a speed improvement. I have not been seeing the expected improvements and have tracked the issue down to the time for multiplying complex matrices. I have made some simple examples in both cases to evaluate the times. The julia example is rough as I am new to julia. #!/usr/local/bin/julia module TmMlt ENV["CMPLXROOT"] = "/home/martin/Dropbox/…
