I want to make the final column to go to zero once I go past a certain flag number
k = 10
a = zeros(1:k)
if b < 1
a = (end 0)
end
I think it looks something like this but I know it isn't exactly right
please help

Ran in:
k = 10
k = 10
a = ones(3,k)
a = 3×10
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
b = -1;
if b < 1
a(:,end) = 0;
end
a
a = 3×10
1 1 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 0
