WebJan 27, 2024 · Method 1: Creating a correlation matrix using Numpy library. Numpy library make use of corrcoef () function that returns a matrix of 2×2. The matrix consists of … Webtorch.cov. Estimates the covariance matrix of the variables given by the input matrix, where rows are the variables and columns are the observations. A covariance matrix is a square matrix giving the covariance of each pair of variables. The diagonal contains the variance of each variable (covariance of a variable with itself).
