@Deprecated
public interface BigMatrix
extends AnyMatrix
```
Deprecated.
as of 2.0, replaced by FieldMatrix with a BigReal parameter

Interface defining a real-valued matrix with basic algebraic operations, using BigDecimal representations for the entries.
Matrix element indexing is 0-based -- e.g., getEntry(0, 0) returns the element in the first row, first column of the matrix.
