MATLAB: Subscript indices must either be real positive integers or logicals.

Question

here is what i have for code

  u=8;
  v=7;
  w=1;
  x=2;
  y=9;
  z=8;
  n=(u/12) + 0.1;
  U=1 + ((w + 1)/((3*x) + 1));
  R=2.58283;
  \ %------------------------------------------------------------------------%




  %Values of 
  %------------------------------------------------------------------------%
  \ r=linspace(0,R);
  %------------------------------------------------------------------------%
  \ 
  %Values of Vprof
  %------------------------------------------------------------------------%
  \ m=1+(1/n);
  Vprof=(((3*n)+1)/(n+1))*(U(((R).^2.3043)-(r).^2.3043)/R.^2.3043)
  \ %------------------------------------------------------------------------%
  \ end

I just have no idea how to proceed as i keep getting the error

Answer 1

prof=(((3*n)+1)/(n+1))*(U(((R).^2.3043)-(r).^2.3043)/R.^2.3043)

In this line, you try to reach a element of U by indexing but U is a scalar numeric value and you can only reach U(1). Check this part.
