Matlab helper function for interpolating loss of coaxial RG58 cable as function of frequency per unit length.

	function dBLossPerM = RG58_loss(f)
	% Function for estimate RG58 coaxial cable loss as a function of frequency
	% per meter. Data is drawn from https://www.w4rp.com/ref/coax.html and is
	% not varified with real lab measurments. Take it with a
	% grain of salt.
	%
	% Output interpolates from the spaced data points. This is for estimating
	% only.

Some Matlab code for generating random normal vectors uniformly distributed in angle

	%% First a method using quaternions
	qtn = randrot(1000,1);

	pts = rotatepoint(qtn, [1 0 0]);

	figure()
	scatter3(pts(:,1), pts(:,2), pts(:,3))
	axis equal
