WebThe MUNIT function returns a unit matrix for a given dimension, n, with a size of n x n.The unit matrix is also called the identity matrix. The MUNIT function takes just one argument, dimension, which should be a positive integer. The resulting matrix contains ones on the main diagonal and zeros in every other position. WebIn mathematics, particularly linear algebra, a zero matrix or null matrix is a matrix all of whose entries are zero. It also serves as the additive identity of the additive group of matrices, and is denoted by the symbol or followed by subscripts corresponding to the dimension of the matrix as the context sees fit.
