In this tutorial, we will explore NumPy's numpy.linalg.eig () function to deduce the eigenvalues and normalized eigenvectors of a square matrix . Let A A be a square matrix. In Linear Algebra, a scalar λ λ is called an eigenvalue of matrix A A if there exists a column vector v v such that. Av =λv A v = λ v.

Consider the two-dimensional vector $${\displaystyle Y=(U,V)}$$ which has components that are bivariate normally distributed, centered at zero, and independent. Then $${\displaystyle U}$$ and $${\displaystyle V}$$ have density functions $${\displaystyle f_{U}(x;\sigma )=f_{V}(x;\sigma )={\frac … See more In probability theory and statistics, the Rayleigh distribution is a continuous probability distribution for nonnegative-valued random variables. Up to rescaling, it coincides with the chi distribution with two degrees of freedom. … See more The probability density function of the Rayleigh distribution is where See more Given a random variate U drawn from the uniform distribution in the interval (0, 1), then the variate $${\displaystyle X=\sigma {\sqrt {-2\ln U}}\,}$$ has a Rayleigh distribution with parameter See more An application of the estimation of σ can be found in magnetic resonance imaging (MRI).
