Hi all, I'm new at Scilab, just started using version 4.1 on Mac OSX.

I am trying to input a fairly complex equation and I inexplicably get

an "error 2 - invalid factor" when I try to evaluate my equations.

Sometimes I get it and sometimes I don't.

What exactly is the root cause of this error? Sometimes my equation

won't work, then I will retype it exactly and it works. I don't

understand, and can't find any useful documentation from my searching

so far. Any help would be appreciated.

I can try to post an example if that will help, but sometimes it will

be as simple as f=tan(2) - and get this error. I retype it and then it

works.

the error usually arises because of a "syntax error", at a point where

the scilab parser could at best expect a numeric factor within an

expression. For instance

-->f=tan(2) -

!--error 2

invalid factor

-->f=tan(2)&

!--error 2

invalid factor

-->f=)

!--error 2

invalid factor

Apparently, if it works the time you retype, it is because you typed

it wrong in the first place. If you're absolutely sure that is not the

case, that might a bug worth investigating.
