MATLAB: Error using parfor on for loop

Question

Hi Please I am getting the followign error running parfor. kindly assist

fnP = @ (a,i) ( sum ( a(i) > a(1:i) + 0.5));
a = mova (:, :);

I am using

parfor j = 1 : mf
    m{j} = (fnP(mova, j);
end

I am getting the error below:

Error using parfor_sliced_fcnhdl_check (line 9)

The sliced variable fnP must not refer to a function handle. To invoke the function handle in the parfor loop, use "feval(fnP, args)". For more information see Parallel Computing Toolbox, "parfor".

Error in kiamean (line 50)

parfor j = 1 : mf

Answer 1

Did you try the suggestion from the error message, i.e.

parfor j = 1:mf
    m{j} = feval(fnP, mova, j);
end

That should work.
