WebIn single variable calculus, you learned that the derivative of a function f: R → R (confused?) at a single point is just a real number, the rate of increase of the function (i.e., slope of the graph) at that point. We could think of that number as a 1 × 1 matrix, so if we like, we could denote the derivative of f ( x) at x = a as Webnumpy.diff. #. Calculate the n-th discrete difference along the given axis. The first difference is given by out [i] = a [i+1] - a [i] along the given axis, higher differences are calculated by using diff recursively. The number of times values are differenced. If zero, the input is returned as-is. The axis along which the difference is taken ...
