3D matrix subtraction
显示 更早的评论
I have the following loop. The problem is I cannot get different values for NSSST as i and j changes
clear i j
for i=1:12
for j=1:12:324
NSSST=SST(:,:,j)-SSST(:,:,i);
j=j+1;
end
i=i+1;
end
end

First of all, the clear is not necessary at all. Secondly you don't need to increment i and j because the for loops do that automatically for you. Third, you're not indexing NSSST so you're just overwriting a scalar every iteration. Maybe you want:
for i = 1 : 12
for j = 1 : 12 : 324
NSSST(i, j) = SST(:,:,j) - SSST(:,:,i);
end
end

But you don't get scalars, but 2d matrices as results from the subtraction ...
Maybe something like
count = 0;
for i = 1 : 12
for j = 1 : 12 : 324
count = count + 1;
NSSST(:,:,count) = SST(:,:,j) - SSST(:,:,i);
end
end
