checkPos {multIntTestFunc}

Domain check for [0,\infty)^n

Description

The function checks if a point (one row in the input argument) is inside [0,\infty)^n = \times_{i=1}^n [0,\infty) or not. In this case the return values are all TRUE. If the input matrix contains entries that are not numeric, i.e., not representing real numbers, the function throws an error. The dimension n is automatically inferred from the input matrix and is equal to the number of columns.

Usage

checkPos(x)

Arguments

x

Matrix with numeric entries. Each row represents one point

Value

Vector where each element (TRUE or FALSE) indicates if a point is in [0,\infty)^n
