mesh

lq.mesh(x, y, ..transforms)

Creates a rectangular mesh from two input arrays. One or more functions are evaluated for each possible pair $(x_i,y_j)$ of the inputs $\{x_0,...\}$ and $\{y_0,...\}$.

#lq.mesh((0, 1), (4, 5), (x, y) => (x + y))

Returns the array (x, y, ..zs) where zs are two-dimensional arrays

(
  (f(x0, y0), f(x0, y1), ...),
  (f(x1, y0), f(x1, y1), ...),
  ...
)

for each function that was passed to mesh().

Parameters

x : array

Array of $x$ coordinates.

y : array

Array of $y$ coordinates.

..transforms : function

Bivariate functions that take two numbers x, y as inputs.
