// The pre-processor constants in this file determine how ulab behaves:
//
// - how many dimensions ulab can handle
// - which functions are included in the compiled firmware
// - whether the python syntax is numpy-like, or modular
// - whether arrays can be sliced and iterated over
// - which binary/unary operators are supported
//
// A considerable amount of flash space can be saved by removing (setting
// the corresponding constants to 0) the unnecessary functions and features.

// Values defined here can be overridden by your own config file as
// make -DULAB_CONFIG_FILE="my_ulab_config.h"
