Question

Suppose that i am using a function ‘fun’ that computes a 3-dimensional vector. What i want is to create, using a for loop, a matrix having the vectors ‘fun’ computes each time as its rows.

thanks,
Nikos

Answer 1

This depends on how many times are you going to be running the function ‘fun’? Let’s call that ‘n’.

% if you know the number of times you are going to run 'fun' you can initialize the final 
matrix to be output = zeros(n,3);

n = 5;

output = zeros(n,3);

for i=1:n
    output(i,:) = fun(); % and you have to give whatever parameters 'fun' takes here
end

I’m not sure if that totally answers your question but it should be enough to get you started.
