Find the first incidence of 1 in a logical vector and replace all other 1s by zero

I need to find the first incidence of 1 in a logical vector and replace all other 1s by zero.

For example, I have a logical vector like this: V = [ 0 1 0 0 1 0 1 ] and I need a function/code that will tell me that will yield V=[0 1 0 0 0 0 0]..

Since I am having a matrix (10000,35) size, how to run this code for each row?

 Wanted = (cumsum(matrix, 2) == 1) .* matrix

diff([zeros(size(YourMatrix,1),1),~cumprod(~YourMatrix,2)],[],2)

Thank you the first one already did the job :)
