Type Members

  1. trait Add extends ScalarOp
  2. type AddOp[T] = BinOp[Add, T, T, T]
  3. trait AndOp extends ScalarOp
  4. trait BinOp[O <: OpType, -X, -Y, +Z] extends AnyRef

    Concrete implementations of BinOp provide primitive-specialized support for performing binary operations on elements of the following objects, as well as the objects themselves:

    Concrete implementations of BinOp provide primitive-specialized support for performing binary operations on elements of the following objects, as well as the objects themselves:

    Appropriate BinOp instances have to be made available in an implicit context in order for the org.saddle.ops.NumericOps methods inherited by the structures above to operate in a seamless fashion.

    For example:

    Vec(1,2,3) * Vec(4,5,6) == Vec(4,10,18)

    The multiplication above relies on two BinOp implementations: the first is BinOp[Multiply, Vec, Vec, Vec], whose implementation in turn relies on BinOp[Multiply, Int, Int, Int].

    NumericOps provides a mix-in trait for mathematical objects, which in Saddle include:

    NumericOps provides a mix-in trait for mathematical objects, which in Saddle include:

    The methods of this trait allow certain element-wise operations involving these objects to be expressed more naturally as mathematical expressions.

    For instance:

    Vec(1,2,4) << 1 == Vec(2,4,8)
Vec(1,2,4) + Vec(3,5,7) == Vec(4,7,11)
Vec(1,2,4) dot Vec(3,5,7) == 41
    This

  32. sealed trait OpType extends AnyRef

    All operations on Saddle objects are defined via instances of subtypes of the trait OpType.

    All operations on Saddle objects are defined via instances of subtypes of the trait OpType. The instances further derive from ScalarOp or MatrixOp, depending on whether the second operand is a scalar or higher-dimensional object.

Value Members

  1. object BinOps extends BinOpMat with BinOpMatInPlace with BinOpVec with BinOpVecInPlace with BinOpFrame with BinOpSeries

    Contains implementations of primitive binary ops that are NA-aware

    Contains implementations of primitive binary ops that are NA-aware

    Double primitive has NA bit pattern baked into its representation, but for others we must check for the appropriate sentinel value.

    Note scala.Function2 is not specialized on Boolean inputs, only output
