Functions
int	b_eml_find (const boolean_T x[5], int i_data[])
	Finds the index of the last `true` element in a 5-element boolean array.

	Finds the index of the last `true` element in a 6-element boolean array.

Detailed Description

Provides MATLAB Coder helper functions to find indices of true values.

Author: Francesco Abate, MSA (Originally generated by MATLAB Coder)

Version: 24.2 (MATLAB Coder version)

Date: 2024-12-03

This auto-generated helper file from MATLAB Coder provides C equivalents of the MATLAB find() command. The functions search a boolean array and return the index of the last element that is true.

These functions are used as low-level utilities by the cdEvaluation function to determine the correct indices for lookup table interpolation within the MPC controller.

Function Documentation

◆ b_eml_find()

int b_eml_find	(	const boolean_T	x[5],
		int	i_data[]
	)

Finds the index of the last true element in a 5-element boolean array.

Parameters

[in]	x	The 5-element boolean input array to search.
[out]	i_data	An output array where the found index will be stored. The index is 1-based, matching MATLAB's convention.

Returns: The number of true elements found (0 or 1). Returns 0 if no true elements are found, and 1 if at least one is found.
