Difference between Ellipsoid and Positive-definite matrix

Ellipsoid vs. Positive-definite matrix

An ellipsoid is a surface that may be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation. In linear algebra, a symmetric real matrix M is said to be positive definite if the scalar z^Mz is strictly positive for every non-zero column vector z of n real numbers.

Similarities between Ellipsoid and Positive-definite matrix

Ellipsoid and Positive-definite matrix have 6 things in common (in Unionpedia): Covariance matrix, Eigenvalues and eigenvectors, Positive-definite matrix, Real number, Spectral theorem, Symmetric matrix.

Covariance matrix

In probability theory and statistics, a covariance matrix (also known as dispersion matrix or variance–covariance matrix) is a matrix whose element in the i, j position is the covariance between the i-th and j-th elements of a random vector.

Eigenvalues and eigenvectors

In linear algebra, an eigenvector or characteristic vector of a linear transformation is a non-zero vector that changes by only a scalar factor when that linear transformation is applied to it.
