I'm using octave to drive the testing of a pattern recognition
program. An octave script generates a pattern, stores it in a
file and starts an external process which processes the data.
i.e. a loop around a construct like:
---
V = blah();
fdx=fopen(tmpFile, 'w');
fprintf(fdx, '%d\n', V);
fclose(fdx);
[result,s] = system(['/home/james/newthing <' tmpFile ]);
---
millions of times. Well after only a few 10s of thousands of times
I see errors like:
error: unable to start subprocess for `/home/james/newthing </tmp/7241Data.dat'
error: evaluating index expression near line 24, column 14
error: evaluating assignment expression near line 24, column 12
... etc.
And at that point even "ls" produces errors:
---
octave:27> ls
error: couldn't start process for ls!
error: evaluating expression near line 27, column 1
---
Any clues ?
Thanks
James
