Skript takes much longer in Octave than in Matlab

[Martin Marmsoler]

Hi,

sorry that I'm asking again, but on the last mail I didn't get a response.

I have a script which I wrote in Matlab and tested it in Octave to, but there I saw that the program takes in Octave much longer than in Matlab R2018a. I have some matrix multiplications in some classes and a few loops but don't understand from where the duration difference come.

Here is the output of profexplore:

Was made with fA = 200 (matlab R2018a needs 0.6s).
