mxIsClass (External Interfaces Reference)

Determine if mxArray is member of 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
logical

object
single
struct
uint8

uint16
uint32
<class_name>
unknown

`cell`	`char`	`double`	`function_handle`
`int8`	`int16`	`int32`	`logical`
`object`	`single`	`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

Logical 1 (true) if pm points to an array having category classname, and logical 0 (false) 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.
