Functions
boolean_T	rtIsInf (real_T value)
	Checks if a double-precision value is positive or negative infinity.
boolean_T	rtIsInfF (real32_T value)
	Checks if a single-precision value is positive or negative infinity.
boolean_T	rtIsNaN (real_T value)
	Checks if a double-precision value is Not-a-Number (NaN).
boolean_T	rtIsNaNF (real32_T value)
	Checks if a single-precision value is Not-a-Number (NaN).

Variables
real_T	rtInf
	Global constant for positive infinity (double precision).
real_T	rtMinusInf
	Global constant for negative infinity (double precision).
real_T	rtNaN
	Global constant for Not-a-Number (double precision).
real32_T	rtInfF
	Global constant for positive infinity (single precision).
real32_T	rtMinusInfF
	Global constant for negative infinity (single precision).
real32_T	rtNaNF

This auto-generated header file from MATLAB Coder defines global constants for infinity (Inf) and Not-a-Number (NaN), and provides wrapper functions to check for these special values.

Using these wrappers ensures consistent behavior across different compilers and platforms, which is a requirement for code generated from MATLAB. These are low-level utilities used by various control algorithms.
