simplification and preallocation of a symbolic value in matlab script

clc
syms AX0
OG=5;

for z=1:4;

AL(z)=(AP19.*BLOKS(z)-AP20).*(AP16.*BLOKS(z)-AP17)+(AP21.*BLOKS(z)-AP22).*(BLOKS(z)-AP5*AP6*AX0);
end

After running codes, I got value of BLOKS as below which makes my program complicated further. I want to simplify this values and same way value of AL is very complicated to handle further. I also want preallocation of AL.

plz help

                                                       17800/4357 - (18430*AX0)/4357
                                                                      442/1843 - AX0
 9328132096000000/8992587776000001 - (649674899429785690307*AX0)/6025033809920000670

%if true
 vpa(BLOKS,4)

Try something like above using vpa
