Evaluate expression in string
#include "engine.h" int engEvalString(Engine *ep, const char *string);
#include "engine.h" integer*4 engEvalString(ep, string) mwPointer ep character*(*) string
ep Engine pointer
string String to execute
1 if the engine session is no longer running
or the engine pointer is invalid or NULL. Otherwise,
returns 0 even if the MATLAB® engine session
cannot evaluate the command.
engEvalString evaluates the expression
contained in string for the MATLAB engine
session, ep, previously started by engOpen.
On UNIX® systems, engEvalString sends
commands to the MATLAB workspace by writing down a pipe connected
to the MATLAB stdin process. MATLAB reads
back from stdout any output resulting from
the command that ordinarily appears on the screen, into the buffer
defined by engOutputBuffer.
To turn off output buffering in C, use:
engOutputBuffer(ep, NULL, 0);
To turn off output buffering in Fortran, use:
engOutputBuffer(ep, '')
On a Windows® system, engEvalString communicates
with MATLAB software using a Component Object Model (COM) interface.
