format
fun format(formatStr:String):Unit
Sets the format for Koma to display numbers in. For example, calling
format("long") println(randn(3))
will cause println(someMatrix) to show more decimals (precision) than
format("short") println(randn(3))
format() must be called before a .toString() request to a Koma matrix in order to have any effect, but setting it will persist for all printing of matrices until called again with a different format string. The default setting is "long". Supported options are "long", "short", "verylong".
