Dear All,

I need to delete the columns with only one element from this matrix,

A   =[1     1     1     0     0
   1     0     0     0
   0     1     0     0
   0     0     1     1
   0     0     0     1
   0     1     0     0];

I used some command find with loop but it is not correct, is there any efficient idea.

thanks in advance.

Nadia,

A(:,sum(A)==1)=[]
