Parallel for loop
parfor loopvar = initval:endval; statements;
end
parfor (loopvar = initval:endval, M); statements;
end
parfor loopvar = initval:endval; executes a series of MATLAB® statements for values
of statements;
endloopvar between initval and endval,
inclusive, which specify a vector of increasing integer values. The
loop runs in parallel when you have the Parallel Computing Toolbox™ or
when you create a MEX function or standalone code with MATLAB
Coder™.
Unlike a traditional for-loop, iterations are not
executed in a guaranteed order. You cannot call scripts directly in
a parfor-loop. However, you can call functions
that call scripts.
parfor (loopvar = initval:endval, M);
executes statements in a loop using a maximum of statements;
endM workers or
threads, where M is a nonnegative integer.
Perform three large eigenvalue computations using three workers or cores with Parallel Computing Toolbox software:
parpool(3) parfor i=1:3, c(:,i) = eig(rand(1000)); end
If you have Parallel Computing Toolbox software,
see the function reference pages for parfor (Parallel Computing Toolbox) and parpool (Parallel Computing Toolbox) for additional information.
If you have MATLAB
Coder software, see the parfor (MATLAB Coder) function reference page for additional
information.
