strcmp() [1/2]

template<typename T >

bool strcmp	(	const T &	str_a,
		const T &	str_b
	)

Octave string utility functions.

This functions provide a C++ interface to most string functions available in the Octave interpreter.

Specializations for Array may consider its dimensions in addition to the actual string contents.

Attention

Octave's string comparison functions return true when strings are are equal, just the opposite of the corresponding C library functions. In addition, Octave's function only return bool and do not check lexicographical order. True if strings are the same.

Specialization for Array<char>

When comparing whole Array of chars, the actual Array dimensions are significant. A column vector and row vector with the same char array, will still return false.

Referenced by mxArray_base::is_class(), main(), mexGetVariable(), mexPutVariable(), octave_get_sig_number(), and bp_table::parse_dbfunction_params().

strcmp() [2/2]

template<typename T >

bool strcmp	(	const T &	str_a,
		const typename T::value_type *	str_b
	)

True if string is the same as character sequence.

Compares a string to the null-terminated character sequence beginning at the character pointed to by str_b.

Specialization for Array<char>

For purposes of comparison of dimensions, the character sequence is considered to be a row vector.

strcmpi() [1/2]

template<typename T >

bool strcmpi	(	const T &	str_a,
		const T &	str_b
	)

True if strings are the same, ignoring case.

Specialization for Array<char>

When comparing whole Array of chars, the actual Array dimensions are significant. A column vector and row vector with the same char array, will still return false.

Referenced by Fchol(), Feig(), Fjsondecode(), and Fjsonencode().

strcmpi() [2/2]

template<typename T >

bool strcmpi	(	const T &	str_a,
		const typename T::value_type *	str_b
	)

True if string is the same as character sequence, ignoring case.

Specialization for Array<char>

For purposes of comparison of dimensions, the character sequence is considered to be a row vector.

strncmp() [1/2]

template<typename T >

bool strncmp	(	const T &	str_a,
		const T &	str_b,
		const typename T::size_type	n
	)

True if the first N characters are the same.

Specialization for Array<char>

The comparison is done in the first N characters, the actual dimensions of the Array are irrelevant. A row vector and a column vector of the same still return true.

Referenced by octave::almost_match().

strncmp() [2/2]

template<typename T >

bool strncmp	(	const T &	str_a,
		const typename T::value_type *	str_b,
		const typename T::size_type	n
	)

True if the first N characters are the same.

strncmpi() [1/2]

template<typename T >

bool strncmpi	(	const T &	str_a,
		const T &	str_b,
		const typename T::size_type	n
	)

True if the first N characters are the same, ignoring case.

Specialization for Array<char>
