How to use logical operator in syms?

I want to implement the code having logical operators included in syms, but it gives error. Plese help to use logical operators with syms variable.

clear all
clc
syms  x1 x2 x_L x_L1 x_L2 x_r t

L1=(160-x1)*(200-x1)+0.02;
L2=(140-x2)*(200-x2)+0.02;

if (L1<0)
    V1=0;
elseif (0<L1<=0.02)
    V1=L1^2*0.1/(2*0.02)
else
    V1=0.1*(L1^2-0.02/2)
end

Conversion to logical from sym is not possible.

if (L2<0)
    V2=0;
elseif (0<L2<=0.02)
    V2=L2^2*0.1/(2*0.02)
else
    V2=0.1*(L2^2-0.02/2)
end

c1=gama(1)*x1^2+beta(1)*x1+alpha(1)+V1;
c2=gama(2)*x2^2+beta(2)*x2+alpha(2)+V2;

Answer 1

Use piecewise()

Answer 2

[David Hill]

if (double(L1)<0)
    V1=0;
elseif 0<double(L1)&&double(L1)<=0.02
    V1=L1^2*0.1/(2*0.02)
else
    V1=0.1*(L1^2-0.02/2)
end
