clc
clear all
for i=1:4
syms a b c
i;
g=a+b-c;
a(i)=1+i;
b(i)=2+i;
c(i)=3+i;
mu(i)=subs(g,{a,b,c},{a(i),b(i),c(i)});
end
??? Error using ==> sym.subs>flatten at 291
Number of elements in NEW must match number in OLD
Error in ==> sym.subs>mupadsubs at 149
[X,Y] = flatten(X,Y);
Error in ==> sym.subs at 124
G = mupadsubs(F,X,Y);
