vector into column vector
[x]=vec2col(x)
x = (1 x n) or (n x 1) vector
x = (n x 1) vector
vec2col([3:7]) vec2col([3:7]') // both command return: //! 3. ! //! 4. ! //! 5. ! //! 6. ! //! 7. ! grocer_init=vec2col(grocer_init) // Example taken from nls: transforms into a column vector the vector of starting values for the optimisation algorithm. This allows the user to give either a column or a row vector and therefore facilitates her life.
