Description

Various C Matrix API functions require or return an mxClassID argument. mxClassID identifies how the mxArray represents its data elements.

Constants

mxUNKNOWN_CLASS

Undetermined class. You cannot specify this category for an mxArray. However, if mxGetClassID cannot identify the class, it returns this value.

mxCELL_CLASS

Cell mxArray.

mxSTRUCT_CLASS

Structure mxArray.

mxLOGICAL_CLASS

Logical mxArray of mxLogical data.

mxCHAR_CLASS

String mxArray of mxChar data.

mxVOID_CLASS

Reserved.

mxDOUBLE_CLASS

Numeric mxArray of either real or complex data types.

MATLAB® Type	double
C Real Data Type	typedef double mxDouble;
C Complex Data Type	typedef struct { mxDouble real, imag; } mxComplexDouble;

mxSINGLE_CLASS

Numeric mxArray of either real or complex data types.

MATLAB Type	single
C Real Data Type	typedef float mxSingle;

mxUINT8_CLASS

Numeric mxArray of either real or complex data types.

MATLAB Type	uint8
C Real Data Type	typedef uint8_T mxUint8;
C Complex Data Type	typedef struct { mxUint8 real, imag; } mxComplexUint8;

mxINT16_CLASS

Numeric mxArray of either real or complex data types.

MATLAB Type	int16
C Real Data Type	typedef int16_T mxInt16;
C Complex Data Type	typedef struct { mxInt16 real, imag; } mxComplexInt16;

mxUINT16_CLASS

Numeric mxArray of either real or complex data types.

C Complex Data Type	typedef struct { mxInt32 real, imag; } mxComplexInt32;

mxUINT32_CLASS

Numeric mxArray of either real or complex data types.

MATLAB Type	uint32
C Real Data Type	typedef uint32_T mxUint32;
C Complex Data Type	typedef struct { mxUint32 real, imag; } mxComplexUint32;

mxINT64_CLASS

Numeric mxArray of either real or complex data types.

MATLAB Type	int64
C Real Data Type	typedef int64_T mxInt64;
C Complex Data Type	typedef struct { mxInt64 real, imag; } mxComplexInt64;

mxUINT64_CLASS

Numeric mxArray of either real or complex data types.

MATLAB Type	uint64
