mxIsClass (External Interfaces/API Reference)

True if mxArray is a member of the specified class

Fortran Syntax

integer*4 function mxIsClass(pm, classname)
integer*4 pm
character*(*) classname

Arguments

pm
Pointer to an array.

classname
A character array specifying the class name you are testing for. You can specify any one of the following predefined constants.

cell
char
double
function_handle

int8
int16
int32
object

single
sparse
struct
uint8

uint16
uint32
<class_name>
unknown

`cell`	`char`	`double`	`function_handle`
`int8`	`int16`	`int32`	`object`
`single`	`sparse`	`struct`	`uint8`
`uint16`	`uint32`	<`class_name`>	`unknown`

In the table, <class_name> represents the name of a specific MATLAB custom object. You can also specify one of your own class names.

Returns

1 if pm points to an array having category classname, and 0 otherwise.

Description

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

Example

```
mxIsClass(pm, 'double')
```

is equivalent to calling either one of the following

mxIsDouble(pm)

mxGetClassName(pm) .eq. 'double'

It is more efficient to use the mxIsDouble form.
