True if mxArray is a member of the specified class

#include "matrix.h"
bool mxIsClass(const mxArray *array_ptr, const char *name);

Arguments

array_ptr

Pointer to an array.

name

The array category that you are testing. Specify name as a string (not as an enumerated constant). You can specify any one of the predefined constants, which are:


`Value of Name`	`Corresponding Class`
`"double"`	`mxDOUBLE_ARRAY`
`"sparse"`	`mxSPARSE_ARRAY`
`"char"`	`mxCHARACTER_ARRAY`
`"cell"`	`mxCELL_ARRAY`
`"struct"`	`mxSTRUCTURE_ARRAY`
`"single"`	`mxFLOAT_ARRAY`
`"int8"`	`mxINT8_ARRAY`
`"uint8"`	`mxUINT8_ARRAY`
`"int16"`	`mxINT16_ARRAY`
`"uint16"`	`mxUINT16_ARRAY`
`"int32"`	`mxINT32_ARRAY`
`"uint32"`	`mxUINT32_ARRAY`

Or, you can specify one of your own class names.

Returns

true if array_ptr points to an array having category name; otherwise, returns false.

Description

Each mxArray is tagged as being a certain type. Call mxIsClass to determine if the specified mxArray has this type.

Example

See mxIsClass.c in the mx subdirectory of the examples directory.
