I tried to vectorize any of these loops, but I couldn't do it. Strangely, when I try it out 'step-by-step' in the Matlab console, it works, but when changing it in my program (which can be found here) it doesn't work properly anymore.
Can anyone help me vectorize it OR make it otherwise faster? Thank you!
Info:
1. r is either 2,3 or 4
2. valuesBitwiseLonger is a binary number 132bits long
for u = 1 : r ExOr1 = valuesBitwiseLonger(u); ExOr2 = str2num(valuesBitwiseLonger(u + r)); exOrNew(u) = bitxor(str2num(ExOr1), ExOr2); end for l = 2*r : 132 - r + 1 NewExOr = ''; for p = 1 : r NewExOr = horzcat(NewExOr, num2str(exOrNew(p))); end for u = 1 : r ExOr1 = valuesBitwiseLonger(l + u - 1); ExOr2 = str2num(NewExOr(u)); exOrNew(u) = bitxor(str2num(ExOr1), ExOr2); end end
