由正定矩阵的定义即知ATA是正定矩阵。正定矩阵是一种实对称矩阵。正定二次型f(x1，x2，…，xn)=X′AX的矩阵A(或A的转置)称为正定矩阵。在线性代数里，正定矩阵 (positive definite matrix) 有时会简称为正定阵。在双线性代数中，正定矩阵的性质类似复数中的正实数。与正定矩阵相对应的线性算子是...
A positive definite matrix is a symmetric matrix A for which all eigenvalues are positive. - Gilbert Strang I have heard of positive definite quadratic forms, but never heard of definiteness for a matrix. Because definiteness is higher dimensional analogy for whether if something is ...
How to create a positive definite matrix? Positive Definite: A positive definite square matrix represents a quadratic form, this quadratic form is such that when evaluating it in any non-null value the result is always positive. Answer and Explanation: ...
An ellipsoid centered at the origin is defined by the solutions xx to the equation xTMx=1xTMx=1, where M is a positive definite matrix. How can I see why M needs to be positive definite, based on the equation of an ellipse Ax2+Bxy+Cy2=1Ax2+Bxy+Cy2=1 wh...
