x= [15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 0];
a = unique(x);
%Last column of x replaced by "a" i.e [ -45 -30 0 15 30 45 60 90]
y= [15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 -45;
15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 -30;
15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 0;
15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 15;
15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 30;
15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 45;
15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 60;
15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 90;];
value = [15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 -45;
15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 -30;
%row of initial guess "x" should be deleted.
15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 15;
15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 30;
15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 45;
15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 60;
15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 90;];

If I understand your question correctly, here is one way:
x= [15 30 45 60 -45 -30 0 90 15 30 45 60 -45 -30 0 90 15 45 60 -45 -30 0];
a = unique(x);
y = repmat(x,numel(a),1);
y(:,end) = a';
value = y;
rowToRemove = find(x(end)==a);
value(rowToRemove,:) = [];
