Retrieve all output arguments from Future
[B1,B2,...,Bn] = fetchOutputs(F)
[B1,B2,...,Bn] = fetchOutputs(F,'UniformOutput',false)
[B1,B2,...,Bn] = fetchOutputs(F) fetches all outputs of the
Future object F
after first waiting for each element of F to reach the state
'finished'. An error results if any element of
F has NumOutputArguments less than the
requested number of outputs.
When F is a vector of FevalFutures, each output argument is
formed by concatenating the corresponding output arguments from each future in
F. An error results if these outputs cannot be concatenated.
To avoid this error, set the 'UniformOutput' option to
false.
[B1,B2,...,Bn] = fetchOutputs(F,'UniformOutput',false)
requests that fetchOutputs combine the future outputs into cell
arrays B1,B2,...,Bn. The outputs of F can be
of any size or type.
After the call to fetchOutputs, all futures in
F have their 'Read' property set to
true. fetchOutputs returns outputs for all
futures in F regardless of the value of each future’s
'Read' property.
Create an FevalFuture, and fetch its outputs.
f = parfeval(@rand,1,3); R = fetchOutputs(f)

Create an FevalFuture vector, and fetch all its outputs. For efficiency, preallocate an array of future objects before.
F(1:10) = parallel.FevalFuture; for idx = 1:10 F(idx) = parfeval(@rand,1,1,10); % One row each future end R = fetchOutputs(F); % 10-by-10 concatenated output
