[Scilab-users] Symbolic computation in Scilab

[Pablo Fonovich]

Hi:
i think i finally solved your problem
 use this script

Syms n z ;
x1 =(0.33) ^( n )
X1 = %sym_sum (7* x1 *( z ^( - n ) ) ,n ,0 , %inf )
X1=ev(X1,'simpsum=true')
x2 =(0.5) ^( n )
X2 = %sym_sum (6* x2 *( z ^( - n ) ) ,n ,0 , %inf )
X2=ev(X2,'simpsum=true')
X = X1 - X2

i just added the ev instruction after calculating X1 and X2 to simplify the sum...

the result is

 X  =
 
                 7.0        6.0
              --------- - -------
                   33          1
              1 - -----   1 - ---
                  100 z       2 z

that is correct!
