matlab.mex.MexHost Class

Namespace: matlab.mex
Superclasses: handle

Out-of-process host for C++ MEX function execution

Description

Instances of the matlab.mex.MexHost class represent processes created to execute C++ MEX functions. You can execute a C++ MEX function from MATLAB^® in the host process using the feval method of this class. For information on running C++ MEX functions out of process, see Out-of-Process Execution of C++ MEX Functions.

The matlab.mex.MexHost class is a handle class.

Creation

Use the mexhost function to create a matlab.mex.MexHost object.

Methods

Public Methods

feval

Evaluate C++ MEX function in MEX host process

Examples

Create Host Process

Create an object of the matlab.mex.MexHost class using the mexhost function. Use the object to call the feval, which executes your C++ MEX function in the MEX host process.

mexHost = mexhost;
result = feval(mexHost,'MyMexFunction',inputs);
