[jira] [Created] (MATH-831) Add a RealMatrixFormat to create a
string representation of a Matrix similar to RealVectorFormat
Thomas Neidhart created MATH-831:
------------------------------------
Summary: Add a RealMatrixFormat to create a string representation of a Matrix similar to RealVectorFormat
Key: MATH-831
URL: https://issues.apache.org/jira/browse/MATH-831
Project: Commons Math
Issue Type: New Feature
Reporter: Thomas Neidhart
Priority: Minor
Fix For: 3.1
When debugging or testing CM code, it would be very helpful to have a way to display the contents of a matrix on the screen.
The format should be in a way that is similar by other tools by e.g. octave in order to be able to use the result directly in such tools:
[ x1, x2, x3, x4, ...;
x1, x2, x3, x4, ...;
x1, x2, x3, x4, ... ]
[ .. denotes the start of the matrix
, .. denotes the end of an element
; .. denotes the end of a row
] .. denotes the end of the matrix

--------------------------------------
In r1364775 the following changes have been made:
* change the default format to the same one as implemented in AbstractRealMatrix.toString()
* add static final fields DEFAULT_FORMAT and OCTAVE_FORMAT to MatrixUtils with corresponding instances of RealMatrixFormat
* use the default RealMatrixFormat in AbstractRealMatrix.toString()
* update unit tests
