Thomas Neidhart commented on MATH-831:
--------------------------------------
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
> 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
