Hi,
I cannot convert this for loop into a parfor loop: I tried to have a look to the help but I cannot understand how to slice this variable to use the parfor istead of the for loop.
tot_rows = randi([10000,20000],1);
tot_cols = randi([10,500],1);
data = zeros(tot_rows, tot_cols);
for k=1:tot_cols
idx = randi([1 tot_rows], randi([1 tot_rows]), 1);
tmp = rand(length(idx),1);
data(idx,k) = tmp;
end
If I try to use the parfor loop I get the following error, I suppose because "data" array cannot be recalled in this way but I cannot understand how to slice it:
tot_rows = randi([10000,20000],1);
tot_cols = randi([10,500],1);
data = zeros(tot_rows, tot_cols);
parfor k=1:tot_cols
idx = randi([1 tot_rows], randi([1 tot_rows]), 1);
tmp = rand(length(idx),1);
data(idx,k) = tmp;
end
Error using test_for (line 6)
Error: Unable to classify the variable 'data' in the body of the parfor-loop. For more information, see Parallel for Loops in MATLAB, "Solve Variable Classification Issues in parfor-Loops".
Thanks everyone for the help! :)
