oh gosh. Seems nothing but trivial. I will try!
Thank you guys.
Maybe Matlab will still work with .* products between parameters or just the Maple still valid with .~ .
In the first case I guess I can find&replace easily in Matlab coding environment.

Anyway thank you again for supporting me.

Thank you so much

Sincerly

Thanks for answering.

Got you, but Maple command CodeGeneration[Matlab] is not automatically generating the *~ . Sure I can't manually do the substitutions, there are too much rows in the code. 
Maybe i should declare the variables first. Dunno what to do... :-( 

Thanks again
