Examples of SingularMatrixException

javax.vecmath.SingularMatrixException
org.ejml.factory.SingularMatrixException
This exception is thrown if an operation can not be finished because the matrix is singular. It is a RuntimeException to allow the code to be written cleaner and also because singular matrices are not always detected. Forcing an exception to be caught provides a false sense of security. @author Peter Abeles
pythagoras.util.SingularMatrixException
Thrown when inversion is attempted on a singular (non-invertible) matrix.
