Functions ¶

func ARange ¶

func ARange(start int, stop int) []float64

ARange implements `np.ARange` - i.e. returns a list of integers (start, ..., stop - 1) in the form of []float64

func Convolve ¶

func Convolve(a, v []float64, mode ConvolutionMode) []float64

Convolve is a (very naive) implementation of precise discrete convolution. The results are numerically equivalent to `np.convolve(a, v, mode)` - it looks like that `np.convolve` uses precise convolution as well (but not an FFT approximation). TODO: optimize the implementation - the current one has O((M+N)^2) time complexity. Looks like it's possible to achieve at least O(MN).
