Hello guys.
I run a Parallel Toolbox coding which is annkmeans.m. In this coding, I found that, it still used the matlabpool command. Since MATLAB has removed this command and replaced with parpool, anyone knows how to change it? (refer: numChunks)
% chunk the data up
numData = size(X,2) ;
if opts.parallel
numChunks = max(matlabpool('size'), 1) ;
data = Composite() ;
dist = Composite() ;
assign = Composite() ;
for i = 1:numChunks
chunk = i:numChunks:numData ;
data{i} = X(:, chunk) ;
dist{i} = inf(1, numel(chunk), class(X)) ;
assign{i} = zeros(1, numel(chunk)) ;
end
else
numChunks = 1 ;
data = X ;
dist = inf(1, numData, class(X)) ;
assign = zeros(1, numData) ;
end

p = gcp;
p.NumWorkers
Will tell you the number of workers in the pool rather than matlabpool('size')
