org.bouncycastle.pqc.crypto.rainbow.util.ComputeInField.inverse()
This function computes the inverse of a given matrix using the Gauss- Elimination method.
An exception is thrown if the matrix has no inverse @param coef the matrix which inverse matrix is needed @return inverse matrix of the input matrix.If the matrix is singular, null is returned. @throws RuntimeException if the given matrix is not invertible
