How to perform arithmetic operation on sparameters?

I have calculate sparameters of RF circuit for range of frequency. Now I want to perform the operation and getting some error shown below.

hR1 = resistor(50,'R50');

hckt1 = circuit('example2');

add(hckt1,[1 2],hR1)

add(hckt1,[2 3],resistor(100))

setports (hckt1, [1 0],[3 0])

freq = linspace (1e3,2e3,100);

S = sparameters(hckt1,freq,100);

for cont = 1:freq %freq =5 to test

S(:,:,cont) = 5*(S(:,:,cont)) - 10

end

Error :

Operator '*' is not supported for operands of type 'sparameters'.

Would you please let me know how to perform the operation Please?

There is a small error in your script. Here is the corrected one:

hR1 = resistor(50,'R50');
hckt1 = circuit('example2');
add(hckt1,[1 2],hR1)
add(hckt1,[2 3],resistor(100))
setports (hckt1, [1 0],[3 0])
freq = linspace (1e3,2e3,100);
S = sparameters(hckt1,freq,100);
 for cont = 1:numel(freq)   % Iterate for the length of freq  
    S.Parameters(:,:,cont) = 5*S.Parameters(:,:,cont) - 10;
 end
