Compute Choleski factorization of a Matrix in R Programming - chol() Function Last Updated : 06 Nov, 2022 Summarize Comments Improve Suggest changes Share Like Article Like Report chol() function in R Language is used to compute the Choleski factorization of a real symmetric positive-definite square matrix. Syntax: chol(x, ...)Parameters: x: an object for which a method exists. The default method applies to real symmetric, positive-definite matrices Example 1: R # R program to illustrate # chol function # Initializing a matrix with # 2 rows and 2 columns x <- matrix(c(8, 1, 1, 4), 2, 2) # Getting the matrix representation x # Calling the chol() function y <- chol(x) # Getting the Choleski factorization # of the specified matrix y Output: [, 1] [, 2] [1, ] 8 1 [2, ] 1 4 [, 1] [, 2] [1, ] 2.828427 0.3535534 [2, ] 0.000000 1.9685020 Example 2: R # R program to illustrate # chol function # Initializing a matrix with # 2 rows and 2 columns x <- matrix(c(1, 2, 3, 4), 2, 2) # Getting the matrix representation x # Calling the chol() function y <- chol(x) # Getting the Choleski factorization # of the specified matrix y Output: [, 1] [, 2] [1, ] 1 3 [2, ] 2 4 Error in chol.default(x) : the leading minor of order 2 is not positive definite Calls: chol -> chol.default Execution halted Comment More infoAdvertise with us K Kanchan_Ray Follow Improve Article Tags : R Language R Matrix-Function Similar Reads R Tutorial | Learn R Programming Language R is an interpreted programming language widely used for statistical computing, data analysis and visualization.
