I am trying to map some columns from one matrix to another, and have run 
across a problem.  The following example may illustrate:

a=hilb(5);
b(:,[1 2]) = a(:,[1 4]);

This assignment does not work.  In fact, the example

a=hilb(5);
b=ones(5);
b(:,[1 2]) = a(:,[1 4]);

does not work, however, the less precise assignment: 

a=hilb(5);
b=ones(2,10);
b(:,[1 2]) = a(:,[1 4]);

does work.  This appears to be a bug to me, or at least an 
inconsistency.  Any explanations?

Thanks, 

Ben
