I am trying to reassign values to a new matrix as a method of cleaning up / bookeeping / decreasing memory. My current code is as follows.
for i = 1:N,
newMat(i,:) = oldMat(dataVec1 == dataVec2(i), :);
end
This loop takes FOREVER to do as N is very large and length(dataVec1) > N. Is there a way to avoid a for loop to achieve this? I have tried using bsxfun, but the intermediate matrix far exceeds memory.
