How to return two arrays in VEX

[renderfan]

I do calculation on arrays in VEX. It is no problem to write function to return one array but how can I return another array? In python this is easy but I do not know how is possible in VEX.

Thanks in advance!

Use routine-style. For some reason, we cannot define functions returning arrays in Wrangle/Snippet nodes (more generally, array functions defined inside other functions), and we have to use this style for setting single array too.

 

Example for Point Wrangle:

void two_arrays(float a1[]; vector a2[])
{
    a1 = array(1, 2, 3);
    a2 = array({1,2,3}, {4,5,6}, {7,8,9});
}

two_arrays(f[]@array_one, v[]@array_two);

BTW this called side effects.

Thank you very much! I will try do it this way.
