> Currently in the matrix package we have asFormatString() methods to serialize matrices, however there are no corresponding methods to decode the serialized matrices. At the moment I do not think any of the code base uses the matrix asFormatString() methods, however for the Gaussian Mixture Model(GMM) code I am working on I will need to serialize/deserialize covariance matrices.
> The following matrix classes will require decoding methods:
> 1. DenseMatrix
> 2. SparseMatrix
> 3. SparseColumnMatrix 
> 4. SparseRowMatrix
> 5. MatrixView
