This example shows how to calculate the sum and maximum values for x among all

p = parpool('local',4);

x = Composite();

xsum = gop(@plus,x);

xmax = gop(@max,x);

This example shows how to horizontally concatenate the column vectors of x from all

workers into a matrix. It uses the same 4-worker parallel pool opened by the previous

x{1} = [3;30];

x{2} = [1;10];

x{3} = [4;40];

x{4} = [2;20];

res = gop(@horzcat,x);

This example shows how to use an anonymous function with gop to join character strings

with spaces between them. In this case, the strings are created from each worker’s

labindex value.

afun = @(a,b)[a,' ',b]
