Hi, I am new to coding and I seem to be using too many loops/cells which significantly slows down my codes.
I want to define a 200x1 matrix every cell of which is a 8X17 matrix and the cells of this one are 1x3 vectors. The values in the 1x3 vectors are generated randomly (from different sets of data: Hmin, Hmax, and Wmax are 8x17 matrices of data which have been imported as cell arrays. They are simple numbers which provide a range for the randomly generated values in 1x3 vectors.).
I want to run a genetic algorithm and this would define 200 members of my initial populations. I have tried this in MATLAB using cell arrays; but they significantly slow down my code. This is what I have tried in MATLAB.
I would be grateful if someone would help me to avoid this.
P = cell (200, 1);
for i = 1:200
P{i,1} = cell(8, 17);
for j = 1:8
for k = 1:17
P{i,1}{j,k} = zeros(1,3);
P{i,1}{j,k}(1,1) = randi(Hmax{j}(k));
P{i,1}{j,k}(1,2) = randi([Hmin{j}(k),Hmax{j}(k)]);
P{i,1}{j,k}(1,3) = randi(Wmax{j}(k));
end
end
end
Thank you so much.
