Hi all,
I have a function like y-theoretical=A*x+(exp(B/C)/ln(Dx)).x and y-experimental are supplied from experiment; where A=f(x,a,b,c,d); B=f(x,a,b,c,d); C=f(x,a,b,c,d); D=f(x,a,b,c,d), I have the upper and lower limits of a,b,c,d that will result to A,B,C,D and then to curve fitting of y-theoretical to y-experimental ,
my question is how to limit the values of A,B,C,D to do not be lower or exceed some specific values like 0<A<0.85; without limiting the lb or ub of a,b,c,d
