Chiamata di MATLAB da C

Eseguire il codice MATLAB^® da programmi C, utilizzando mxArray

Nota

Le funzioni dell'API Engine per C lavorano con la struttura dati di MATLAB mxArray che è definita nel API Matrix C. Per scrivere applicazioni che utilizzano le feature moderne di C++, vedere Chiamata di MATLAB da C++.

Le applicazioni engine sono programmi autonomi che consentono di chiamare MATLAB dai programmi C/C++ utilizzando MATLAB come engine computazionale. Per compilare un applicazione engine, chiamare la funzione mex.

Le applicazioni engine richiedono una versione installata di MATLAB; non è possibile eseguire MATLAB Engine su una macchina che dispone solo del runtime di MATLAB.

API Engine per C

`Engine`	Type for MATLAB engine
`engOpen`	Start MATLAB engine session
`engOpenSingleUse`	Start MATLAB engine session for single, nonshared use
`engClose`	Quit MATLAB engine session
`engEvalString`	Evaluate expression in string
`engGetVariable`	Copy variable from MATLAB engine workspace
`engPutVariable`	Put variable into MATLAB engine workspace
`engGetVisible`	Determine visibility of MATLAB engine session
`engSetVisible`	Show or hide MATLAB engine session
`engOutputBuffer`	Specify buffer for MATLAB output
