# checkStandardSimplex: Domain check for standard simplex \{\vec{x} \in R^n : x_i >=q... In multIntTestFunc: Provides Test Functions for Multivariate Integration

## Description

The function checks if a point (one row in the input argument) is inside the standard simplex \{\vec{x} \in R^n : x_i ≥q, \Vert x \Vert_1 ≤q 1 \} or not. 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

 1 checkStandardSimplex(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 the standard simplex

## Examples

 1 2 x <- matrix(rnorm(30),10,3) checkStandardSimplex(x)
