Eigenvalue decomposition plays a very vital role in easing the complexity of the matrix in the Linear Algebra field. The square matrix is broken down into simple components, i.e., eigenvalues and their eigenvec
OpenCV通过函数cv2.face.EigenFaceRecognizer_create()生成特征脸识别器实例模型,然后应用cv2.face_FaceRecognizer.train()函数完成训练,最后用cv2.face_FaceRecognizer.predict()函数完成人脸识别。 1.函数cv2.face.EigenFaceRecognizer_create() 函数cv2.face.EigenFaceRecognizer_create()的语法格式为: retval = cv2.fa...
The Monte Carlo method can be used to estimate the multiplication factor, and other eigenvalues, for a nuclear system. In this chapter we present two methods for estimate the eigenvalues of a nuclear system and give implementations for slab geometry. The fission cycle approach uses the definition...

【线性代数】矩阵的特征分解、特征值和特征向量(eigen-decomposition, eigen-value & eigen-vector) 就像我们可以通过质因数分解来发现整数的一些内在性质一样(12 = 2 x 2 x 3),我们也可以通过分解矩阵来发现表示成数组元素时不明显的函数性质。 矩阵分解有种方式,常见的有 特征分解 SVD 分解 三角分解 特征...
