How to create zeros between ones in array

hello,

anyone know a fast way to create zeros between ones in an array?

for example A = [0 0 0 1 1 1 1 0 0 0]

I want it to return B = [0 0 0 1 0 0 1 0 0 0]

I was thinking of doing a double for loop running from the left side and the right. If there is a better way, please let me know. Thanks in advance

Answer 1

[Azzi Abdelmalek]

A=[0 0 0 1 1 1 1 0 0 0]
AA=[0 A 0]
i1=strfind(AA,[0 1])+1
i2=strfind(AA,[1 0])-2
for k=1:numel(i1)
  A(i1:i2)=0;
end
A

B = zeros(size(A));
B([strfind([0 A],[0 1]),strfind([A 0],[1 0])]) = 1;
