each

swordfish.function.each()

Apply a function (specified by func or operator) to each element of args / X / Y.

• For matrices, calculate in each column;

• For tables, calculate in each row;

• For array vectors, calculate in each row;

• For dictionaries, calculate each value.

The data type and form of the return value are determined by each calculation result. It returns a vector or matrix if all calculation results have the same data type and form, otherwise it returns a tuple.

Parameters:

• func (Constant) – A function.

• args (Constant) – The required parameters of func.

• operator (Constant) – A binary operator.

• X (Constant) – A pair/vector/matrix/table/array vector/dictionary.

• Y (Constant) –

  A pair/vector/matrix/table/array vector/dictionary.

  X and Y must have the same dimensions.
