Saving the outputs of multiple runs of a script

I have a stochastic simulation which I would like to run multiple times while changing a variable called 'correlation'.
For each run I would like to save the outputs as individual matrices so I can plot them together and compare values.
How would I go about saving the outputs of each simulation for each corresponding value of correlation?
I tried incorporating this into a 'for' statement but I'm very new to MATLAB and get the error "Array indices must be positive integers or logical values."
My code so far is:
R01= zeros(length(t),maxit);
R02= zeros(length(t),maxit);
R03= zeros(length(t),maxit);
R04= zeros(length(t),maxit);
R05= zeros(length(t),maxit);
R06= zeros(length(t),maxit);
R07= zeros(length(t),maxit);
R08= zeros(length(t),maxit);
R09= zeros(length(t),maxit);
for correlation=(0.1:0.1:0.9)
run stochasticsimulation.m
ResultsR01(:,correlation)= R01;
ResultsR02(:,correlation)= R02;
ResultsR03(:,correlation)= R03;
ResultsR04(:,correlation)= R04;
ResultsR05(:,correlation)= R05;
ResultsR06(:,correlation)= R06;
ResultsR07(:,correlation)= R07;
ResultsR08(:,correlation)= R08;
ResultsR09(:,correlation)= R09;
end
Could you please advise on either where to look to learn this stuff or what improvements I can make to my code.
Thanks!

%if
Count = 0.1:0.1:0.9;
for correlation=1:length(Count)
Change this line in for loop and run it.

You should not be using a script outside of debugging. If you're only interested in the value of a single variable, you should make your script a function with that variable as the output. Then you can run it in a loop.
You should also note that indices in an array must be positive integers:
my_array(0.1) % this is an invalid syntax
my_array(1) % this is a valid syntax
You should also avoid numbering your variables, use indexing instead. If you only store a single value:
%change this
R01=my_function;
R02=my_function;
R03=my_function;
%to this:
R(1)=my_function;
R(2)=my_function;
R(3)=my_function;
