problem with parfor loop
显示 更早的评论
Is it possible to parfor this?
for iter=1:50
for i=1:100
x(:,i)= rand(3,1)
end
end

Sure, especially since the outer loop is not doing anything and can be abandoned.
parfor i=1:100
x(:,i)= rand(3,1)
end

parfor iter=1:50
x=nan(3,100); %initialize
for i=1:100
x(:,i)= rand(3,1)
end
end

No, it's not possible even with normal for loops. The left hand side of
x(iter,i)= rand(3,1)
is 1x1 but the rhs is 3x1.

You can do it, but doing it without loops
x=rand(50,100);
will be faster.
