Okay, my question was not clear enough. You can't choose 'V'
arbitrarily, it must match in dimension with X and Y. 

As your code doesn't include the computation of V, it's impossible to
say whether V is a valid value for mesh().

mesh() plots the values of Z versus the coordinates given by X and Y.
Therefor all three matrices must have the same dimensions. meshgrid()
computes the matrices X and Y such that they have the same dimension,
but for Z, you are on your own. Usually, you compute X and Y and compute
Z as a function of those two, ie

Z = X.^2 + Y.^3.
