new_structured_coordinates

Allocate an array of type float filled with the values representing a matrix of 1, 2 or 3 dimensions for the node coordinates of an structured cartesian mesh of lines, quadrilaterals or hexahedra

<xs> is a list of real values increasing, representing the x coordinate of the grid nodes

<ys> and <zs> are the same, for the y and z cartesian directions respectively
