The variable heuristic_map in a parfor cannot be classified.
显示 更早的评论
I went through tons and tons of documentation, online support, threads here and not only here, and everything implies that my code is perfectly ok, but there is still an error. My code:
parfor biases=1:numel(biass)
for ampl=1:numel(am)
[Amps,PHASES,~,~,~,~,~,~,~]=mod2((biases-1+b1)*biasdist,(ampl-1+am1)*amdist,N,w,action2);
[f_demod,~]=liczenie_P(refindex,sig,Amps,PHASES,k,biases,Omega,action2);
x=f_demod(center-limit:center+limit);
x=resample(x,up,ratio);
dif=abs(numel(x)-len);
x=x(round(dif/2)+shift1:end+shift2-round(dif/2));
x=x/max(x);
ccc=corrcoef(data,x);
cccc=ccc(1,2);
heuristic_map(ampl,biases)=cccc;
end
end
The variable heuristic_map in a parfor cannot be classified.
Please help me

I think the fix here is simple - when using a nested for loop inside a parfor loop, the bounds of that loop must be known to be constant for the duration of the parfor loop (at least if you want to "slice" a variable inside). In this case, you simply need to calculate numel(am) outside the loop, like so:
n_am = numel(am);
parfor biases = 1:numel(biass)
for ampl = 1:n_am
heuristic_map(ampl, biases) = ...;
end
end
This limitation is described in the documentation - see the section entitled Limitations of Nested for-Loops.
