*i need simple example using pmode . for example : if I have this array
x=[2 90 2 17 80; 5 3 2 90 8; 60 74 1 2 3;55 6 4 11 0];
how i can use my two workers to sum this array, where each worker will work on part of array, the collect the result.
I don't know how i partition the array on two workers , the how to collect the results.

Here's an example how to use
distributed
arrays and how to use SPMD:
matlabpool open 2
x = 1:1:100;
y = 100:-1:1;
dx = distributed(x);
dy = distributed(y);
dz = dx + dy
spmd
dz
end
Note that dz is distributed across two workers :-).
Hope this helps

Yes you could use this functionality in the way that you describe. You will need to check documentation for distributed/codistributed arrays to see which options are supported.
You can also do MPI like programming in MATLAB using labSend, labReceive commands, etc.
