The problem is that when I use vpa(U(x,t), 7) to get the solution with 7-digit decimal precision, MATLAB still outputs a very long and complicated expression. how do I fix it?
Observe: a1 = vpa(sym(pi), 7) a2 = vpa(a1, 10) a3 = vpa(a2, 15) a4 = a3 - pi double(a4) From this we deduce that vpa() co...
