Transcribed image text: The reverse of the above exercise does not hold: it is not generally possible to approximate invertible matrices using non-invertible ones. In fact, for any invertible matrix, there is one non-invertible matrix that is closest to it and none can be closer. (a) Thus consider an invertible matrix A.
