WebThe diag () function can extract or replace the diagonal of a matrix and can also construct a diagonal matrix. For example: Code: diag (mat3) Code: diag (diag (mat3)) Output: 8. det () Function The det () function returns the determinant of the input matrix. For example: Code: det (mat2) Output: 9. colSums (), rowSums (), and sum () Functions WebFeb 16, 2024 · Print matrix in diagonal pattern Try It! Approach: From the diagram it can be seen that every element is either printed diagonally upward or diagonally downward. Start from the index (0,0) and print the elements diagonally upward then change the direction, change the column and print diagonally downwards.

WebDiagonal Matrix. A square matrix in which every element except the principal diagonal elements is zero is called a Diagonal Matrix. A square matrix D = [d ij] n x n will be called a diagonal matrix if d ij = 0, … WebOct 24, 2016 · There is also another commonly used method, that involves the adjoint of a matrix and the determinant to compute the inverse as inverse(M) = adjoint(M)/determinant(M). This involves the additional step of computing the adjoint matrix. For a 2 x 2 matrix, this would be computed as adjoint(M) = trace(M)*I - M. Therefore, WebMay 15, 2024 · diagonal <- function (x) { for (i in nrow (x)) { for (j in ncol (x)) { if (i == j) { a <- x [i, j] } } } print (a) } I am passing a matrix to the function.
