Drastic Sum algorithm to fuzzy logic set

I need to implement an algorithm to the fuzzy logic set of a drastic sum between two signals.

Signal a:

a= trimf(x,[2,5,8]);

Signal b:

b=gaussmf(x,[2,3]);

My output s1 would be like:

if min(A,B) = 0 -> max(A,B)

else = 1

Something like:

close all

clear all

clc

x=(0:0.01:10)';

a= trimf(x,[2,5,8]);

b=gaussmf(x,[2,3]);

% Drastic Sum

s1=zeros(1001)';

for y=1:length(x)

if min(a(y),b(y))==0

s1(y)=max(a(y),b(y));

else s1(y)=1;

end

end

z = plot(x,a,x,b,x,s1,'o-');
