} mxClassID;

Constants

mxUNKNOWN_CLASS

The class cannot be determined. You cannot specify this category for an mxArray; however, mxGetClassID can return this value if it cannot identify the class.

mxCELL_CLASS

Identifies a cell mxArray.

mxSTRUCT_CLASS

Identifies a structure mxArray.

mxLOGICAL_CLASS

Identifies a logical mxArray, an mxArray whose data is represented as mxLogical.

mxCHAR_CLASS

Identifies a string mxArray, an mxArray whose data is represented as mxChar.

mxDOUBLE_CLASS

Identifies a numeric mxArray whose data is stored as double-precision, floating-point numbers.

mxSINGLE_CLASS

Identifies a numeric mxArray whose data is stored as single-precision, floating-point numbers.

mxINT8_CLASS

Identifies a numeric mxArray whose data is stored as signed 8-bit integers.

mxUINT8_CLASS

Identifies a numeric mxArray whose data is stored as unsigned 8-bit integers.

mxINT16_CLASS

Identifies a numeric mxArray whose data is stored as signed 16-bit integers.

mxUINT16_CLASS

Identifies a numeric mxArray whose data is stored as unsigned 16-bit integers.

mxINT32_CLASS

Identifies a numeric mxArray whose data is stored as signed 32-bit integers.

mxUINT32_CLASS

Identifies a numeric mxArray whose data is stored as unsigned 32-bit integers.

mxINT64_CLASS

Identifies a numeric mxArray whose data is stored as signed 64-bit integers.

mxUINT64_CLASS

Identifies a numeric mxArray whose data is stored as unsigned 64-bit integers.

mxFUNCTION_CLASS

Identifies a function handle mxArray.

Description

Various mx* calls require or return an mxClassID argument. mxClassID identifies the way in which the mxArray represents its data elements.
