if you run F Zero you will get [2 5], I want to delete the column number 2 and 5 from the Matrix W, but the problem is when I'm deleting the columns it deletes number 2 and 6

clc;
clear;
W=rand(6)
Pt=10;
Pn=[2 7 3 2 8 4];
P = waterfill(Pt,Pn);
F_Zero=find(~P) %Find Zeros
%% delete the columns
if (~isempty(F_Zero)) %There is Zeros (not empty)
for i=1:length(F_Zero) % Loop to Set Columns to Zeros
C_Zero=F_Zero(i);
W(:,C_Zero) = []
end
end

When you are using a loop the ddimension of W changes and it removes the column in the newly obtained W. You need not to use loop. remove columns at once.
clc;
clear;
W=rand(6) ;
Pt=10;
Pn=[2 7 3 2 8 4];
P = waterfill(Pt,Pn);
F_Zero=find(~P) %Find Zeros
%% delete the columns
if (~isempty(F_Zero)) %There is Zeros (not empty)
W(:,F_Zero) = [] ;
end
