i am solving a heat equations with maple but i didn't work out. if you guys can get it out plz give me code. thanx a million

diff(u1(x,t),t)=diff(diff(u1(x,t),x),x))-a*(u1(x,t)-u2(x,t))+b*(u3(x,t)-u1(x,t))
diff(u2(x,t),t)=diff(diff(u2(x,t),x),x))-c*(u2(x,t)-u3(x,t))+a*(u1(x,t)-u2(x,t))
diff(u3(x,t),t)=diff(diff(u3(x,t),x),x))-b*(u3(x,t)-u1(x,t))+c*(u2(x,t)-u3(x,t))

i need the expression of the u1(x,t)，u2(x,t)，u3(x,t) and the a,b,c are constants.

Looking forward to hearing from you!!!
