streamobs.functions module

Function definitions.

class streamobs.functions.Line(slope=0.0, intercept=0.0, **kwargs)

Bases: BoundedFunction

Line function. Evaluated as:

y(x) = slope*x + intercept

class streamobs.functions.Sinusoid(amplitude=1.0, period=1.0, phase=0.0, offset=0.0, **kwargs)

Bases: BoundedFunction

Sinusoid function. Evaluated as:

y(x) = amplitude/2 * cos( 2pi*(x - phase)/period ) + amplitude/2+offset

streamobs.functions.function_factory(type_, **kwargs)

Create a function with given kwargs.

Parameters:

• type (function type)

• kwargs (passed to function init)

• Returns

• -------

• func (the function)
