Why do you calculate the mean of the complete BMEDIA matrix, if you use the output for the element (i,j) only?
A = zeros(size(depthgrid));
for i = 1:length(longitude)
for j = 1:length(latitude)
F = find(-NewZ<depthgrid(i,j));
A(i,j) = mean(B(i,j, min(F):max(F)),3);
end
end
mean() is not really efficient. Try this:
A = zeros(size(depthgrid));
for i = 1:length(longitude)
for j = 1:length(latitude)
F = find(-NewZ<depthgrid(i,j));
F1 = F(1);
F2 = F(numel(F));
A(i,j) = sum(B(i,j, F1:F2), 3) / (F2 - F1 + 1);
end
end
Alternatively:
A = zeros(size(depthgrid));
N = zeros(size(depthgrid));
BB = reshape(BB, [], size(B, 3));
nNewZ = -NewZ;
for k = 1:numel(NewZ) - 1
index = (nNewZ(k) <= depthgrid < nNewZ(k+1));
A(index) = A(index) + BB(index, k);
N(index) = N(index) + 1;
end
A = A ./ N;
There is an indexing problem in this version, therefore I assume the result is not correct yet. Without matching input arguments I cannot debug it currently. Try to fix this code by your own.
