30. def apply(f: (Int, Int, Double) ⇒ Double): Matrix

31. def apply(f: (Double) ⇒ Double): Matrix

    A version of function apply with default AUTO treatment of evalZeros.

32. def apply(f: (Int, Int, Double) ⇒ Double, evalZeros: T): Matrix

    Apply a function element-wise without side-effects to the argument (creates a new matrix).

    Apply a function element-wise without side-effects to the argument (creates a new matrix).

    f

    element-wise function (row, column, value) ⇒ "new value"

    evalZeros

    Do we have to process zero elements? true, false, auto: if auto, we will test the supplied function for f(0) != 0, and depending on the result, will decide if we want evaluation for zero elements. WARNING: the AUTO setting may not always work correctly for functions that are meant to run in a specific backend context, or non-deterministic functions, such as {-1,0,1} random generators.

    returns

    new DRM with the element-wise function applied.
