Check if a Matrix is Symmetric or not in R Programming - isSymmetric() Function Last Updated : 16 Jun, 2020 Summarize Comments Improve Suggest changes Share Like Article Like Report isSymmetric() function in R Language is used to check if a matrix is a symmetric matrix. A Symmetric matrix is one whose transpose is equal to the matrix itself. Syntax: isSymmetric(x) Parameters: x: Matrix to be checked Example 1: Python3 1== # R program to check if # a matrix is symmetric # Creating a diagonal matrix x1 <- diag(3) # Creating a matrix x2 <- matrix(c(1, 2, 2, 3), 2) # Calling isSymmetric() function isSymmetric(x1) isSymmetric(x2) Output: [1] TRUE [1] TRUE Example 2: Python3 1== # R program to check if # a matrix is symmetric # Creating a matrix x1 <- matrix(c(1:9), 3, 3) # Calling isSymmetric() function isSymmetric(x1) Output: [1] FALSE Comment More infoAdvertise with us N nidhi_biet 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.
