C Syntax

Arguments

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 the MATLAB stdin. Any output resulting from the command that ordinarily appears on the screen is read back from stdout into the buffer defined by engOutputBuffer. To turn off output buffering, use

Under Windows on a PC, engEvalString communicates with MATLAB using a Component Object Model (COM) interface.

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.
