Hi,
I have a m*n matrix where some of rows are like these for exmaple
[-1,-0.65,-0.45,0,0.3,0.8,1,0.4,0.2,-0.1]
Now I need to make new row as follows
[-1,-0.65,-0.45,0,0.3,0.8,1,0,0,0]
that is once any of the elements in row becomes 1 after that all the elements will be zero.

For a matrix run a loop through the rows
x=[-1,-0.65,-0.45,0,0.3,0.8,1,0.4,0.2,-0.1]
%Code edited according to the question
x(find(x==1,1)+1:end)=0

This deletes all elements after a 1. The OP asked for setting the values to 0.
find() can reply an empty matrix or a vector. This works, but only, because the colon operator ignores all elements of the vector except for the 1st one. This is at least confusing.

You are correct, Jan, my code doesn't do what OP asked. The code written is according to what I had in mind at the time.
I will edit my code accordingly.
