I'm trying to solve an equation to find variable Sw and there are variables that are vectors but i don't know how to solve it all at once without having to define each value in the vector separately.
I also wonder if the equation can be solved using conditional statement. Below is the code including the vector Rw and Sw. Thank you
function Sw= Sw(n,m,p,Qv,B,Rw,Rt,SW)
n=2.2;
m=1.86;
p=0.153;
Qv=0.980;
B=3.200;
Rw=0.265;
Rt=[4.05; 4.10; 4.22; 4.30; 4.38; 4.54; 4.82; 5.03; 5.23; 5.43; 5.64; 5.80;6.24; 6.49; 6.61;6.73; 6.73; 6.69; 7.01; 7.50; 7.78; 8.15; 8.27; 8.47; 9.24; 9.97; 10.58;10.95; 11.39; 11.64; 12.00; 12.41; 13.46; 13.91; 15.20; 19.28; 21.08;22.83;24.77; 26.23; 28.06; 30.17;31.02; 31.50];
SW=[1.000; 0.998; 0.962; 0.938; 0.913; 0.895; 0.883; 0.871; 0.859; 0.840; 0.822; 0.816; 0.775; 0.763; 0.751; 0.745; 0.739; 0.721; 0.702; 0.684; 0.666; 0.654; 0.642; 0.611; 0.590; 0.563; 0.557; 0.549; 0.531; 0.519; 0.500; 0.488; 0.476; 0.458; 0.391; 0.361; 0.342; 0.324; 0.318; 0.306; 0.294; 0.288; 0.285; 0.276];
Sw=sqrt(n)(Rw/((p^m)*Rt*(1+(Qv*B*Rw)/Sw)));
end

There is already a eq for Sw... Please explain the use of conditional statement.
