Evaluate expression in character array
integer*4 function engEvalString(ep, command)
integer*4 ep
character*(*) command
ep
Character array to execute.
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.
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.
