In the code that you have shared whichDistance is an empty matrix. So when you do
raw(whichDistance, :)=[];
raw array doesn't change and when you do
nValDis = size(raw,1)
It returns number of rows in raw array which is 3 I suppose.
To achieve what you need, you should count 1s and 0s in the whichDistance matrix. One of the way could be:
whichDistance = cell2mat(Distances)==0;
nD0 = sum(sum(whichDistance)); % Number of 1s, sum(sum()) to calculate total sum of matrix
if nD0 >0
fprintf('\nThis team had %d distances that did not count.\n',nD0);
end
nValDis = numel(whichDistance)-nD0 % total number of elemets - element with 1s = element with 0s
