def check_arrays	(	self,
		sample_x,
		points_to_add = `1`
	)

Make sure arrays are big enough to add the specified number of points

Parameters:

	sample_x	A sample abscissa vector or scalar to determine the shape of the arrays to build.
	points_to_add	The number of points to be appended in the next operation (at least).
