# Grid kron.m

Spherical grid direct product.

## Syntax

    [angles,weights]=grid_kron(angles1,weights1,angles2,weights2)


## Description

Tiles one grid using the rotations of the other. Grids should be supplied using Euler angles in three columns [alphas betas gammas] in radians.

## Arguments

   angles1 - angles of the first grid, as [alpha beta gamma], rad

weights1 - weights of the first grid

angles2 - angles of the second grid, as [alpha beta gamma], rad

weights1 - weights of the second grid


## Returns

    angles - angles of the product grid, as [alpha beta gamma], rad

weights - weights of the product grid


## Examples

Grid files are located in kernel/grids directory.

## Notes

The function is provided for research purposes, but it is generally not a good idea to obtain spherical grids by taking direct products of smaller ones. Use repulsion.m to obtain very good grids of any size.
