Changing numbers in a matrix by checking values

Dear all,

I have the following 3x50 Matrix wiht true and false values:

Ende =

     0     1     0
     0     0     0
     0     1     0
     0     0     1
     1     0     1
     0     0     1
     1     0     1
     0     0     1
     1     0     1
     1     1     1
     0     0     1
     0     1     0
     0     0     0
     0     0     1
     0     0     1
     0     1     0
     1     1     0
     0     1     0
     0     1     0
     0     0     1
     0     0     0
     0     0     0
     1     0     1
     0     0     0
     1     0     1
     1     0     1
     1     0     1
     0     1     0
     0     1     0
     1     0     1
     0     0     0
     0     0     1
     1     1     1
     0     1     0
     0     0     1
     1     1     1
     0     0     1
     0     1     0
     0     1     0
     0     0     0
     0     1     0
     0     1     0
     0     0     0
     0     0     1
     0     0     1
     0     0     1
     1     0     1
     0     0     1
     0     0     0
     0     1     0

In every line with 1 1 0 or 1 1 1: If in column 3 the value is 0 than I need to change the value in column 2 into 0 --> I want to make in the matrix out of 1 1 0 , a new updated line 0 1 0. Same for 1 1 1 --> I want to change those lines into 1 0 1.

Is anyone around who could help on this?

Cheers, Felix

 matrix out of 1 1 0 , a new updated line 0 1 0

This changes the first column, not the second one.

[EDIT]

a = [0 1 0;1 0 1];
[l0,ii] = ismember(Ende,[1 1 0;1 1 1],'rows');
Ende(l0,:) = a(ii(l0),:);

Thanks for the quick response, I copied the code, but I got not the result i hoped to get, the matrix is not changing :/

[Andrei Bobrov]

I'm fixed.

In Matlab >= R2016a:

index = (Ende == [1 1 0]);
Ende(index, 1) = 0;
index = (Ende == [1 1 1]);
Ende(index, 2) = 0;
