Method arange

src/array.rs:696–707

Return evenly spaced values within a given interval. See [numpy.arange][numpy.arange] for the Python API and [PyArray_Arange][PyArray_Arange] for the C API. # Example ``` use numpy::{PyArray, PyArrayMethods}; use pyo3::Python; Python::attach(|py| { let pyarray = PyArray::arange(py, 2.0, 4.0, 0.5); assert_eq!(pyarray.readonly().as_slice().unwrap(), &[2.0, 2.5, 3.0, 3.5]); let pyarray = PyArray
