Universal functions (ufunc) — NumPy v1.4 Manual (DRAFT)

Web21 jul. 2010 · There are currently more than 60 universal functions defined in numpy on one or more types, covering a wide variety of operations. Some of these ufuncs are called automatically on arrays when the relevant infix notation is used ( e.g., add (a, b) is called internally when a + b is written and a or b is an ndarray ). Webnumpy.trapz(y, x=None, dx=1.0, axis=-1) [source] # Integrate along the given axis using the composite trapezoidal rule.
