MATLAB Application Program Interface Reference

Evaluate expression in character array

integer*4 function engEvalString(ep, command)
integer*4 ep
character*(*) command

Arguments

ep

Engine pointer.

command

Character array to execute.

Description

engEvalString evaluates the expression contained in command 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.

Example

See fengdemo.f in the eng_mat subdirectory of the examples directory for a sample program that illustrates how to call the MATLAB engine functions from a Fortran program.

Note: Fortran engine routines are not available on Windows.
