Standard Matrix code in java?

Question

I am new to Java, and I need a Matrix class. Is there a standard library/package for this, or I will have to write it myself?

Thanks

Answer 1

No, there is no "matrix class" built into the standard libraries.

Yes, there are many linear algebra libraries available. For example:
