How to turn multiple outputs into a array
显示 更早的评论
I have N=60
for n=1:N
Rate2Graph=Rate_overtime(5,5,n);
end
This gives an answer for each time step. How can I take all those answers and put them into an array?

Assuming Rate_overtime is a function that outputs a double scalar, you could do this:
Rate2Graph = zeros(1,N);
for n=1:N
Rate2Graph(n) = Rate_overtime(5,5,n);
end
If Rate_overtime is simply a 3D array, then you could do the above, or you could do this:
Rate2Graph = squeeze(Rate_overtime(5,5,1:N));

Following on from this, I tend to do away with the loop by using a cell2mat, i.e.
Rate2Graph = cell2mat({Rate_overtime(5,5,1:N)});
This notation is particularly helpful when you have an array or structure that you wish to dig into and you do not want to loop over every value in turn.
For example, given the 1xN NormalDistribution array, P, one may wish to pull out the mean value from each N:
P(1:N).mu would give N results
{P(1:N).mu} wraps everything into a cell array
using a cell2mat then returns the values in a single array:
cell2mat({P(1:N).mu})
