??? Attempt to reference field of non-structure array.

Following code is for manipulating matrix of image to change color of some pixel

for row=1:rows     
     for col=1:columns       
         s=I(row,col);
         if(s.Equals(0))
             ...... end end end

I am getting following error ??? Attempt to reference field of non-structure array.

In MATLAB syntax,

s.Equals

is referencing a field named "Equals" in a structure named "s".

Are you trying to test if s is equal to zero? If so, then you want

if s==0
