I have two independent functions:
1: [outputs1]=doModulation(inputs1)
2: LIVE_GUI(input2) % it is a real-time inspector
and my current job is to run both of them simultaneously.
I have installed the Parallel Computing Toolbox and tried the code like this:
parpool(2)
parfor i = 1:2
if i == 1
[parameter1, parameter2]=doModulation(inputs1); % the parameter1 and 2 will be used for the following function
else
LIVE_GUI(input2) % input2 is a struct
end
end
...
[parameter3, parameter4]do_another_process(parameter1, parameter2,...);
But after 10 seconds I received an error message:
Brace indexing is not supported for variables of
this type.
Error in Main_Fcn (line 179)
parfor i = 1:2
Does anybody know how to solve that? Or should I try some other options? Thank you!

I have tried that, but it does not work either. And I get the following error message:
Error using parpool (line 113)
Found an interactive session. You cannot have
multiple interactive sessions open
simultaneously. To terminate the existing
session, use 'delete(gcp('nocreate'))'.

Close all the MATLAB session running on your computer and try again.
ALTERNATIVELY
You can try without using parpool command.
