四元四次方程组怎么写程序，求举个例子
solve[a + 298.05*b + (298.05^2)*d + (298.05^3)*d == 0.529213,
a + b*303.05 + c*303.05^2 + d*303.05^3 == 0.526236,
a + b*307.95 + c*307.95^2 + d*307.95^3 == 0.522834,
a + b*312.93 + c*312.93^2 + d*312.93^3 == 0.519023,a,b,c,d]
这么写为什么算不出来？
优质解答
Solve[{a + 298.05*b + (298.05^2)*d + (298.05^3)*d == 0.529213,a +b*303.05 + c*303.05^2 + d*303.05^3 == 0.526236,a + b*307.95 + c*307.95^2 + d*307.95^3 ==0.522834,a + b*312.93 + c*312.93^2 + d*312.93^3...
