Package edu.northwestern.at.utils.math.matrix Description

Methods for working with two-dimensional matrices stored as arrays of doubles. The code here is based in part on the following existing matrix libraries for Java.

• JAMA, a public domain library from a cooperative venture by The MathWorks and the National Institute of Standards and Technology (NIST).
• JMAT, a library by Yann Richet, licensed under the LGPL.
• JMatrices, a library by Piyush Purang, licensed under the LGPL. In particular, the overall breakdown of package methods is modeled after the JMatrices implementation.
