I want to identifiy the entry elements (i.e., the first "1" value) in the rows of the following logical matrix
input_matrix = [1 1 1; 0 1 1; 0 0 0; 0 1 0];
the expected matrix would be the following:
output_matrix = [1 0 0; 0 1 0; 0 0 0; 0 1 0];
The position of the "entries" (first "1" values) in both input and output matrices is respected. Also, Further "1" values (following the entries) have been replaced with "0" values.
Thanks in advance for any hint.

@julian gaviria Just a note -
My and Stephen's code did exactly what was asked.
You should have clarified what exactly you wanted, in your question statement. The comments on my code clearly indicated what the code does, and you should have picked up from them that it is not what you want to do and mentioned it in reply to that.
I will be deleting my solution.

in = [1 1 1; 0 1 1; 0 0 0; 0 1 0];
M=size(in,1);
temp=[zeros(M,1), in];
d=diff(temp,1,2);
out=(d==1)

This wouldn't work if there is a 1 after a 0
in = [1 1 0 1; 0 1 1 1; 0 0 0 0; 0 0 1 0];
M=size(in,1);
temp=[zeros(M,1), in];
d=diff(temp,1,2);
out=(d==1)
