how to run two independent functions in matlab?

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!

Did you try just dropping the brackets?

outpus1=doModulation(inputs1);

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'))'.

p.s. the outputs are parameters

Close all the MATLAB session running on your computer and try again.

ALTERNATIVELY

You can try without using parpool command.
