I have a 100 X 1 (n1) cell array with each cell holding indices of a bigger data set(100 X 100, n2). I made a nested loop in order to access each individual element(index) and compare the values of another data set with these indices with a if condition. If the condition succeeds, I want to delete that element from the original cell array into a new cell array. However when I set the element to [] in matlab, the value of the cell array does not change. The code is below:
for i = 1:length(n1) for j = 1:length(n1{i, 1}) if n2(i,n1{i,1}(1,j)) > n3(i) && n2(i, n1{i,1}(1,j)) > n4(n1{i, 1}(1, j)) n1{i,1}(1,j) == []; end end end 1 Answer
I take that n1(i,1) is always a row vector so you should use,
n1{i,1}(j) = []; If n1(i,1) is not a column or row then removing an element from middle would be impossible.
for example:
A = {[1 2 3],[5 8 9]} A{1,2}(1,2) = [] gives the error: A null assignment can have only one non-colon index.
But A{1,2}(2) = [] is okey.
