Solve a simple system of linear equations using sparse matrices. Consider the matrix equationA*x = B. A = sparse([0 2 0 1 0; 4 -1 -1 0 0; 0 0 0 3 -6; -2 0 0 0 2; 0 0 4 2 0]); B = sparse([8; -1; -18; 8; 20]); x = A\B ...
定义三次方程:首先,需要定义一个三次方程,例如:y = ax^3 + bx^2 + cx + d。其中,a、b、c、d为方程的系数。 求解方程:使用MATLAB的solve函数来求解方程。假设方程的系数分别为a、b、c、d,可以使用以下代码求解方程:roots([a, b, c, d])。该函数将返回方程的根。 绘制方程曲线:使用MATLAB的plot函数...
3、scipy.linalg的solve(A,b)结果竟然跟我的一样,继续深入研究下solve函数 scipy.linalg.solve(a,b,sympos=False,lower=False,overwrite_a=False,overwrite_b=False,debug=False,check_finite=True) Solve the equation ax = b for x. sympos:boolean,a是对称正定矩阵 lower:bool,optional,默认是上三角矩阵 If...
