* Reads a matrix from a file.

*
|

* Matrix files have a simple format that's supposed to be easy to create with

* a text editor or a spreadsheet.
|

*
|
||||
* The first line has four numbers for width, height, scale and
|
||||
* offset (scale and offset may be omitted, in which case they default to 1.0
|
||||
* and 0.0). Scale must be non-zero. Width and height must be positive
|
||||
* integers. The numbers are separated by any mixture of spaces, commas,
|
||||
* tabs and quotation marks ("). The scale and offset fields may be
|
||||
* floating-point, and must use '.'
|
||||
* as a decimal separator.
|
||||
*
|
||||
* Subsequent lines each hold one line of matrix data, with numbers again
|
||||
* separated by any mixture of spaces, commas,
|
||||
* tabs and quotation marks ("). The numbers may be floating-point, and must
|
||||
* use '.'
|

* as a decimal separator.

*

* Extra characters at the ends of lines or at the end of the file are
