Functions

func TestTimeFreqTransformForwardReverse

func TestTimeFreqTransformForwardReverse(t *testing.T, f transform.Transform)

TestTimeFreqTransformForwardReverse runs the transform twice, first with an impulse, then again with that transform output, to see if the original impulse is recovered.

func TestTimeFreqTransformGivenImpulse

func TestTimeFreqTransformGivenImpulse(t *testing.T, f transform.Transform)

TestTimeFreqTransformGivenImpulse sends a shifted impulse through the forward FFT. See http://www.sccon.ca/sccon/fft/fft3.htm

func TestTimeFreqTransformGivenShiftedImpulse

func TestTimeFreqTransformGivenShiftedImpulse(t *testing.T, f transform.Transform)

TestTimeFreqTransformGivenShiftedImpulse sends a shifted impulse through the forward FFT. See http://www.sccon.ca/sccon/fft/fft3.htm

func VerifyEqualWithin

func VerifyEqualWithin(t *testing.T, expected, actual []complex128, delta float64)

VerifyEqualWithin verifies that the given slices are the same length, and that all elements (real and imaginary components) are within the given delta of eachother.
