Why won't it go through the ifelse statement when the if statement isn't satisfied?

A= zeros(3,10);
A(1,:,:)=[1:10];
B=.5+rand(1,10)*.4;
A(2,:,:)=B;
C=round(1+rand(1,10)*7);
A(3,:,:)= C;

team_A= zeros(3,5);
team_B= zeros(3,5);
for d=[1:1:10]

    k=9;
    if rem(d,2)==1;
    for e=[1:1:j]

        p=e;
        team_A(:,2,:)=A(:,p,:);
        A(:,p)=NaN;

Then it doesn't loop as well.

It is highly unlikely that any random element in the second row of A would happen to be exactly equal to the maximum integer of the third row in the line

if A(2,f,:)== max(C)

The odds are one in a thousand million million or thereabouts. For that reason it is equally unlikely that the 'elseif' would ever lead to a change in team_B.
