Parameters:

matrix - the match and mismatch costs

gap - the cost for a gap

Throws:

CloneNotSupportedException - if matrix could not be cloned

MatrixCosts

public MatrixCosts(StringBuffer xml)
            throws NonParsableException

Restores MatrixCosts object from its XML representation.

Parameters:

xml - the XML representation

Throws:

NonParsableException - if the XML could not be parsed
