The meaning of SYMMETRIC MATRIX is a matrix that is its own transpose.
注:压缩存储的矩阵可以分为特殊矩阵和稀疏矩阵。对于那些具有相同元素或零元素在矩阵中分布具有一定规律的矩阵,被称之为特殊矩阵。对于那些零元素数据远远多于非零元素数目,并且非零元素的分布没有规律的矩阵称之为稀疏矩阵。元素以主对角线为对称轴对应相等的矩阵。 2楼2023-10-09 14:27 回复 l-ygw 对角矩阵...
Find the Hessian matrix of the function f(x,y,z)=sin(xyz) We now compute the second partial derivatives of f : Therefore the Hessian matrix of f is: 6. Positive Definite In linear algebra, a symmetric n*n real matrix M is said to be positive-definite if the scalar z^TMz is stri...

Symmetric matrix example, A = [11−1120−105] The transpose of A (AT) = [11−1120−105] Since, A= AT matrix A is a symmetric matrix. NOTE: If any diagonal matrix is equal to the transpose of the matrix, such matrices are automatically symmetric. Before We Move Further, Let ...
