MATLAB: How do I find a number that matches a certain condition and mark it as "0"?
For example,
A = [1 0 1 1 0 -1 0 1 -1] for i = 1: length(A)
how to mark number as "0" when sum(A(1:i)) ~= 1 && sum(A(1:i)) ~= 0
?
and how to write the code?

A = [1 0 1 1 0 -1 0 1 -1]
%# create all sums from 1 through i
sa = cumsum(A);
%# in output: ith element is true if sum from
%# 1 through the ith element in A is 0 or 1
output = ismember(sa,[0 1])
output =
1 1 0 0 0 0 0 0 0
