fetchNext

Retrieve next unread outputs from FevalFuture array.

Syntax

• [idx, y1, ... , ym] = fetchNext(f)

• [idx, y1, ... , ym] = fetchNext(f, timeout)

Input argument

• f - FevalFuture object

• timeout - timeout seconds: waits for a maximum of timeout seconds for a result in f to become available.

Output argument

• idx - Index of the FevalFuture array, returned as an integer scalar.

• y1, ... , ym - outputs

Description

[idx, y1, ... , ym] = fetchNext(f) retrieves index idx of the new readable FevalFuture object in the array f that is finished, and m results from that FevalFuture as Y1, ... , Ym.

Example

tic()
N = 100;
for idx = N:-1:1
    F(idx) = parfeval(backgroundPool,str2func('rank'),1,magic(idx));
end
results = zeros(1,N);
for idx = 1:N
    [finishedIdx, result] = fetchNext(F);
    results(finishedIdx) = result;
    disp(sprintf('Result: %d', result));
end
toc()
