以下是一个MATLAB函数示例,实现了调用格式为`H=mat_roots(A,n)`的函数,其中A是方矩阵,n是整数,H是一个单元数组,每个单元存储矩阵A的一个n次方根:```matlabfunctionH=mat_roots(A,n)[V,D]=eig(A);%计算矩阵A的特征向量和特征值D_root=D.^(1/n);%计算特征值的n次方根H=V*D_root*inv(V);%构...
The roots function calculates the roots of a single-variable polynomial represented by a vector of coefficients. For example, create a vector to represent the polynomial x2−x−6, then calculate the roots. p = [1 -1 -6]; r = roots(p) r = 3 -2 By convention, MATLAB® returns...
