Problems encountered in Parallel Processing
显示 更早的评论
Dear All,
I tried to use parfor to run my code which is given as follows:
function [A,B] = temp_test(x)
a = [1:2*x]; b = [1:x];
A = zeros(1,x); B = zeros(x,1);
parfor i = 1 : x
j = x + 1;
c = func1(a(j),b(i));
A(i) = c;
B(i) = a(j) + b(i);
end
function [d] = func1(e,f)
d = e*f;
end
end
But I was told I can not call func1 like this because it is a nested function. Would anybody tell me how I can fix this problem but I still want to keep the func1 as it is?
Thanks a lot.
Benson

Is there any reason not to simply make func1 a local function?
function [A,B] = temp_test(x)
a = [1:2*x]; b = [1:x];
A = zeros(1,x); B = zeros(x,1);
parfor i = 1 : x
j = x + 1;
c = func1(a(j),b(i));
A(i) = c;
B(i) = a(j) + b(i);
end
end
function [d] = func1(e,f)
d = e*f;
end

I don't think you read my initial post carefully. If you look, you will see that I did not relocate the code of func1 inside the parfor loop. I simply made it into a local function. You could also move func1 to its own file. This might be a good idea if its code is as long and involved as you say.
