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;`
C Complex Data Type	`typedef struct { mxSingle real, imag; } mxComplexSingle;`

mxINT8_CLASS

Numeric mxArray of either real or complex data types.

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.

MATLAB Type	`uint16`

mxINT32_CLASS

Numeric mxArray of either real or complex data types.

MATLAB Type	`int32`
C Real Data Type	`typedef int32_T mxInt32;`
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;`
