Validates a transition matrix. Checks that each entry of the matrix is a non-negative number and that each row add up to 1.

Usage

M	A candidate transition matrix.

Value

A character string specifing the cause of invalidation, or the matrix itself if it is valid.

Examples

A <- matrix(c(0.33, 0.66, 0.00, 0.00,
               0.16, 0.17, 0.66, 0.00,
               0.50, 0.00, 0.50, 0.00,
               0.00, 0.00, 0.00, 0.00), nrow = 4, byrow = TRUE)
mat_val(A)
