[Scilab-users] case control statement

[Claus Futtrup]

Hi there

OK, so I converted to elseif (source code at the bottom of my post). Now 
Scilab complains like this:

     elseif or[(model==3) (model==4)] then // FDD-LOG / CLOG
              !--error 35
Syntax error in a 'if' instruction.
at line      11 of function getq called by :
endfunction

I'm replacing a CASE control with an ELSEIF and using the OR[] to 
collect my options. I tested the OR control on the command line, without 
problems, so I don't understand what Scilab is complaining about.

Please let me know if you have any idea...

Best regards,
Claus

Here's a code snippet:

// This function, getq, defines the q-values for all models.

if  model==1  then  // FDD
        //
        // q = 1 - this used to be 1 - beta*ln(w) also for FDD (!?!?)
     q  =  1;

elseif  or[(model==3)  (model==4)]  then  // FDD-LOG / CLOG
          //
          // q = 1 - beta * ln(w) - Scilab log(w) = natural log = ln(w))
     q  =  1  -  gbeta*log(w);  // gbeta - it's _not_ LOG model _lambda_

elseif  model==2  then  // LOG
        //
        // q = 1 - beta*ln(iw)
        //
     q  =  1  -  gbeta*log(%i  .*  w);

end
