[scilab-Users] index error not helpful

[Julio Gonzalez-Saenz]

I assumed you forgot the variable  "n"  in plot(phz) when copy and paste, don't you??

Otherwise, I can't see why you get the error.. and we dont.

This is what I get. Line 7 is the plot command.


 plot(phz)
          !--error 21 
Invalid index.

at line       7 of exec file called by :    
exec('/test if.sce', -1)
