JLFloat64VectorFunctions2

jarray64.spad line 231 [edit on github]

This package provides operations which all take as arguments JLFloat64Vector and functions from JLFloat64 to JLFloat64. The operations all iterate over their vector argument and either return a value of type JLFloat64Vector or a JLFloat64.

map: (JLFloat64 -> JLFloat64, JLFloat64Vector) -> JLFloat64Vector

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

map: (JLFloat64 -> Union(JLFloat64, failed), JLFloat64Vector) -> Union(JLFloat64Vector, 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: ((JLFloat64, JLFloat64) -> JLFloat64, JLFloat64Vector, JLFloat64) -> JLFloat64

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

scan: ((JLFloat64, JLFloat64) -> JLFloat64, JLFloat64Vector, JLFloat64) -> JLFloat64Vector

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.
