engEvalString (MATLAB Application Program Interface)

Evaluate expression in string

C Syntax

#include "engine.h"
int engEvalString(Engine *ep, const char *string);

Arguments

ep

Engine pointer.

string
String to execute.

Description

engEvalString evaluates the expression contained in string for the MATLAB engine session, ep, previously started by engOpen. It returns a nonzero value if the MATLAB session is no longer running, and zero otherwise.

On UNIX systems, engEvalString sends commands to MATLAB by writing down a pipe connected to MATLAB's stdin. Any output resulting from the command that ordinarily appears on the screen is read back from stdout into the buffer defined by engOutputBuffer.

Under Windows on a PC, engEvalString communicates with MATLAB via ActiveX.

Examples

(UNIX) See engdemo.c in the eng_mat subdirectory of the examples directory for a sample program that illustrates how to call the MATLAB engine functions from a C program.

(Windows) See engwindemo.c in the eng_mat subdirectory of the examples directory for a sample program that illustrates how to call the MATLAB engine functions from a C program for Windows.
