checkUnitSphere {multIntTestFunc} | R Documentation |
Domain check for unit sphere
Description
The function checks if a point (one row in the input argument) is inside the unit sphere 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
is automatically inferred from the input matrix and is equal to the number of columns.
The function allows for an additional parameter
to test
.
WARNING: Due to floating point arithmetic the default value of
will not work properly in most cases.
Usage
checkUnitSphere(x, eps = 0)
Arguments
x |
Matrix with numeric entries. Each row represents one point |
eps |
Non-negative numeric that allows to test points with an additional tolerance |
Value
Vector where each element (TRUE or FALSE) indicates if a point is in the unit sphere
