check.infinityM: Check Infinity in Matrix

In tropicalSparse: Sparse Tropical Algebra

Description

check.infinityM checks infinite value in a matrix based on algebraType input.

Usage

check.infinityM(M, algebraType)

Arguments

M	is matrix.
algebraType	is string input that can be minplus or maxplus.

Details

The input of this function is a matrix and type of tropical algebra. A matrix may contain infinite values that can be positive or negative. Both the positive and negative infinite values works differently on each algebra type. Due to the difference between minplus and maxplus tropical algebra, it is important to manage them so they can work in their own bounderies. In minplus -Inf cannot be used while in maxplus Inf cannot be used. So the main purpose of this funnction is to check such possibilities that can cause errors. If this function finds a -Inf in the matrix and the type of algebra is minplus then the function generates an error. Similarly, if the function finds a Inf in the matrix and the type of algebra is maxplus then the function also generates an error.

Value

Returns nothing but generates an error if specific conditions met.

Examples

nrow = 3, ncol = 3, byrow = TRUE)
check.infinityM(a, 'minplus')
