JuliaFloat64VectorFunctions2

jarray64.spad line 231 [edit on github]

This package provides operations which all take as arguments JuliaFloat64Vector and functions from JuliaFloat64 to JuliaFloat64. The operations all iterate over their vector argument and either return a value of type JuliaFloat64Vector or a JuliaFloat64.

map: (JuliaFloat64 -> JuliaFloat64, JuliaFloat64Vector) -> JuliaFloat64Vector

map(f, v) applies the function f to every element of the vector v producing a new vector containing the values.

map: (JuliaFloat64 -> Union(JuliaFloat64, failed), JuliaFloat64Vector) -> Union(JuliaFloat64Vector, failed)

map(f, v) applies the function f to every element of the vector v producing a new vector containing the values or "failed".

reduce: ((JuliaFloat64, JuliaFloat64) -> JuliaFloat64, JuliaFloat64Vector, JuliaFloat64) -> JuliaFloat64

reduce(func, vec, ident) combines the elements in vec using the binary function func. Argument ident is returned if vec is empty.

scan: ((JuliaFloat64, JuliaFloat64) -> JuliaFloat64, JuliaFloat64Vector, JuliaFloat64) -> JuliaFloat64Vector

scan(func, vec, ident) creates a new vector whose elements are the result of applying reduce to the binary function func, increasing initial subsequences of the vector vec, and the element ident.
