help creating a matrix from data in a for loop.

I have

hrs = 24

Iterations/Hr = 60

for k = 1:hrs

for b = 1: iterations/hr

'conditions'

end

end

how do i take the data from the loops and put it into a 60x24 matrix in order to be able to find max, min, and average of each hour.

hrs = 24; % 24 hours
iterations = 60; % 60 iterations per hour
data = zeros(iterations,hrs); % initialize data to be a 60-by-24 matrix of zeros
for k = 1:hrs
    for b = 1:iterations
        data(b,k) = k*b; % some result based on 'conditions' (or whetever else)
    end
end

% min, max, and average, by hour
min_by_hour = min(data);
max_by_hour = max(data);
avg_by_hour = mean(data);

% same thing, but explicitly saying to operate along the first dimension of data
min_by_hour = min(data,[],1);
max_by_hour = max(data,[],1);
avg_by_hour = mean(data,1);
