RE: Problem in a if condition

Pol,

The "error" comes about because you have invoked error.  This gives your
original error message and a traceback in subsequent lines.  These are not
new errors.  If you want to trap the error and have execution continue, use
the try/catch blocks (enter > help try).  Alternatively, set an error flag
to tell your programme that bad things are happening and use disp("message")
or fprintf(1,"message",[]) to output to the console.

Regards

Paul Thomas

no it's not a trick I just want octave to print the error then write
nothing.

Here I get 4 errors ... 

maybe it's a trick for you but i'm pretty new and I do my best to
understand it.

Why do I get: error: evaluating if command near line 10, column 3 ?? 

the syntax is correct ... 

 tell me what's wrong.
