mxSTRUCT_CLASS
Identifies a structure mxArray.
Identifies a user-defined (nonstandard) mxArray.
Identifies a string mxArray; that is an mxArray whose data is represented as mxCHAR's.
Identifies a sparse mxArray; that is, an mxArray that only stores its nonzero elements.
Identifies a numeric mxArray whose data is stored as double-precision, floating-point numbers.
Identifies a numeric mxArray whose data is stored as single-precision, floating-point numbers.
mxINT8_CLASSIdentifies a numeric
mxArray whose data is stored as signed 8-bit integers.
mxUINT8_CLASSIdentifies a numeric
mxArray whose data is stored as unsigned 8-bit integers.
mxINT16_CLASSIdentifies a numeric
mxArray whose data is stored as signed 16-bit integers.
mxUINT16_CLASSIdentifies a numeric
mxArray whose data is stored as unsigned 16-bit integers.
mxINT32_CLASSIdentifies a numeric
mxArray whose data is stored as signed 32-bit integers.
mxUINT32_CLASSIdentifies a numeric
mxArray whose data is stored as unsigned 32-bit integers.
mxINT64_CLASSReserved for possible future use.
mxUINT64_CLASSReserved for possible future use.
mxUNKNOWN_CLASS = -1The class cannot be determined. You cannot specify this category for an
mxArray; however, mxGetClassID can return this value if it cannot identify the class.
Various mx calls require or return an mxClassID argument. mxClassID identifies the way in which the mxArray represents its data elements.
