error evaluating binary operator

[Emily Moberg]

Hi!
I have the following for loop
[m,o]=size(A)
for n=1:o

idx=find(A(:,n)==0);

if length(idx)>=m*(.7);

A(:,n)=[];

endif;

endfor;

and I keep getting an error evaluating binary operator '=='  for the idx=find(A(:,n)==0) line. I'm not sure what I'm doing wrong... I'm still rather new at this, so sorry if this is a trivial question!

Thanks!

Emily
