How to repeat a function several times?

Hello everyone,

I have a function that calculates the time series of a growth rate assuming that the growth rate follows an AR(1) process. So the value t1 depends on t0 and so on. I do this procedure for different sample sizes. How can I repeat this function, say 1000 times, in the way, that the calculation begins from t0 for each simulation path and that the output is a ((1000*samplesize),x) matrix.

Thank you in advance.

Just preallocate the output array and call the function in a loop saving each simulation in row/column of the array depending on which orientation you wish.

Alternatively, could use arrayfun but the loop will probably out-perform it....
