NAME ^

Bio::Matrix::MatrixI - An interface for describing a Matrix

SYNOPSIS ^

  # Get a Matrix object

DESCRIPTION ^

This is an interface describing how one should be able to interact with a matrix. One can have a lot of information I suppose and this outline won't really work for PWM or PSSMs. We will have to derive a particular interface for those.

FEEDBACK ^

Mailing Lists

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing list. Your participation is much appreciated.

Support

Please direct usage questions or support issues to the mailing list:

bioperl-l@bioperl.org

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.
