Subscript indices must either be real positive integers or logicals.

Hello all, this is my code

xyb= a two dimensional matrix storing x,y coordinates for some points
Y= meshgrid output

for i=1:30

      dist=(xyb(2i,1)-xyb((2i-1),1))*(xyb(2i,2)-Y(10,1))/(xyb(2i,1)-xyb( (2i-1),1) )
  end

But I am getting this error... can anyone please help

Answer 1

2i is the way to encode complex(0,2), which is to say 0 + 2*sqrt(-1).

If you want to multiply your "i" variable by 2, use multiplication, 2*i

It is not recommended to use "i" as a variable name because of its existing use as the complex constant.
