matclass: Matrix Class

Description

matclass gives the name of the class of the matrix. If the class of the matrix elements is numeric or integer, the matrix class is real by default.

Usage

matclass(M, real = TRUE)

Arguments

M

a matrix, of any type and dimensions.

real

a logical value. Set to FALSE if you want to opt out of the default treatment of numeric or integer elements.

Examples

A <- matrix(c(1, 2, 2+3i, 5), ncol = 2)  # complex matrix
B <- matrix(1:4, ncol = 2)  # real matrix
C <- matrix(c(TRUE, TRUE, FALSE, FALSE), ncol = 2)  # boolean matrix
D <- matrix(c('a', 'b', 'c', 'd'), ncol = 2)  # character matrix
E <- matrix(c(1,2+3i,'a',TRUE),ncol=2)  # 1 single character makes it a character matrix
