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: Identifies a cell mxArray.
mxSTRUCT_CLASS: Identifies a structure mxArray.
mxLOGICAL_CLASS: Identifies a logical mxArray, an mxArray of mxLogical data.
mxCHAR_CLASS: Identifies a string mxArray, an mxArray whose data is represented as mxChar.
mxVOID_CLASS: Reserved.
mxDOUBLE_CLASS: Identifies a numeric mxArray whose data is stored as the type specified in the MATLAB Primitive Types table.
mxSINGLE_CLASS: Identifies a numeric mxArray whose data is stored as the type specified in the MATLAB Primitive Types table.
mxINT8_CLASS: Identifies a numeric mxArray whose data is stored as the type specified in the MATLAB Primitive Types table.
mxUINT8_CLASS: Identifies a numeric mxArray whose data is stored as the type specified in the MATLAB Primitive Types table.
mxINT16_CLASS: Identifies a numeric mxArray whose data is stored as the type specified in the MATLAB Primitive Types table.
mxUINT16_CLASS: Identifies a numeric mxArray whose data is stored as the type specified in the MATLAB Primitive Types table.
mxINT32_CLASS: Identifies a numeric mxArray whose data is stored as the type specified in the MATLAB Primitive Types table.
mxUINT32_CLASS: Identifies a numeric mxArray whose data is stored as the type specified in the MATLAB Primitive Types table.
mxINT64_CLASS: Identifies a numeric mxArray whose data is stored as the type specified in the MATLAB Primitive Types table.
mxUINT64_CLASS: Identifies a numeric mxArray whose data is stored as the type specified in the MATLAB Primitive Types table.
mxFUNCTION_CLASS: Identifies a function handle mxArray.

Description

Various MX Matrix Library functions require or return an mxClassID argument. mxClassID identifies the way in which the mxArray represents its data elements.

The following table shows MATLAB types with their equivalent C types. Use the type from the right-most column for reading mxArrays with the mxClassID value shown in the left column.

`mxINT16_CLASS`	`int16`	`int16_T`	`short`
`mxUINT16_CLASS`	`uint16`	`uint16_T`	`unsigned short`
`mxINT32_CLASS`	`int32`	`int32_T`	`int`
`mxUINT32_CLASS`	`uint32`	`uint32_T`	`unsigned int`
`mxINT64_CLASS`	`int64`	`int64_T`	`long long`
`mxUINT64_CLASS`	`uint64`	`uint64_T`	`unsigned long long`
`mxSINGLE_CLASS`	`single`	`float`	`float`
