If I have multiple function, then how can I get the function of min(fun1,fun2,fun3,...)?

If there are functions like
R1(x), R2(x), R3(x), R4(x)
then when I need to draw new funcion graph that show the min value function for x
like
min(x)= min(R1(x),R2(x),...)
how can I code this function?

xmin=min([R1(x(:)');R2(x(:)');...]); % to get a correct result, the argument must be a row-vector: x(:)' turns any input array to it; do not use "min" for your inner variables as it is the name of the inbuilt matlab function
plot(x,xmin,'.-');
