Functions

func Argument

func Argument(test bool)

Panics with "illegal argument" if test is false.

func Assert

func Assert(test bool)

Panics with "assertion failed" if test is false.

func AssertMsg

func AssertMsg(test bool, msg interface{})

Panics with msg if test is false

func FatalErr

func FatalErr(err interface{}, msg ...interface{})

If err != nil, trigger log.Fatal(msg, err)

func Fprint

func Fprint(out io.Writer, array ...interface{})

Produces nicely formatted output for multi-dimensional arrays.

func Fprintf

func Fprintf(out io.Writer, format string, array ...interface{})

Produces nicely formatted output for multi-dimensional arrays.

func FprintfFloats

func FprintfFloats(out io.Writer, format string, a [][][]float32)

ZZ <-> XX
YZ <-> XY
XZ <-> XZ
XY <-> YZ
