sym(___,"clear")clears assumptions set on a symbolic variable or array. You can specify"clear"after the input arguments in any of the previous syntaxes, except combining"clear"andset. You cannot set and clear an assumption in the same function call tosym. sym(num)converts a number or ...

If you just want to evaluate this formula given your variables then:テーマコピーA1 = 1;A2 = 2;A3 = 3;L1 = 11;L2 = 22;L3 = 33;Px = ( L1 + L2*cos(A2) + L3*cos(A2+A3) )*cos(A1)will give you the answer.solve(Px==(L1+L2*cos(A2)+L3*cos(A2+A3))*cos(A1), Py==...
问题的根源在于，被积函数表达式里面含有符号变量（sym），而quad函数是采用数值方法计算积分，根本不适用于含有符号变量的场合。可以尝试用计算符号积分的 int 函数来求：syms D R rsyms xdf=(r.^2*acos((r-(D-(R-sqrt(R.^2-x.^2)))./r)-(r-(D-(R-sqrt(R.^2-x.^2))).*sqrt(r...
