[___] = eig(___,outputForm) returns the eigenvalues in the format specified by outputForm, using any of the input or output arguments mentioned earlier. Set outputForm to "vector" to get the eigenvalues in a column vector, or "matrix" to get them in a diagonal matrix. Examples for ...
Firstly, the eigenvalues and eigenvectors of matrix A can be calculated using the eig function: [V, D] = eig(A) The results are: V = [2.0000, -0.4472; 3.0000, 0.8944] D = [2.0000, 0; 0, 3.0000] Where V is the matrix of eigenvectors, and D is the matrix of eigenvalues. With ...
在MATLAB中,eig函数用于计算矩阵的特征值和特征向量。该函数的语法如下: [eigenvectors, eigenvalues] = eig(matrix) 其中,matrix 表示要计算特征值和特征向量的矩阵,eigenvectors 表示计算得到的特征向量,eigenvalues 表示计算得到的特征值。 例如,下面的代码示例计算了一个矩阵的特征值和特征向量: A = [1 2; 3 4...
Then, we use eig() to find the eigenvalues and store them in EigenValues.To sort these eigenvalues, we extract the diagonal elements of EigenValues using the diag() function and sort them using MATLAB’s sort() function. This gives us the sorted eigenvalues in ascending order, along with ...
