Re: Error with dim_vector

[Justin Bare]

I was originally just doing:

data(v) = Cell((octave_value)var);

but this gives me a compiler error that says "error: conversion from ‘int’
to non-scalar type ‘dim_vector’ requested" which is why i changed it to
the dim_vector.
In that case, could you tell me how to get rid of this error with the
normal indexing operator?
