phasecalc function

Phase from Cosinor Estimates

Calculate the phase given the estimated sine and cosine values from a cosinor model.

phasecalc(cosine, sine)

Arguments

• cosine: estimated cosine value from a cosinor model.
• sine: estimated sine value from a cosinor model.

Returns

• phaser: Estimated phase in radians.

Details

Returns the phase in radians, in the range $[0,2\pi)$. The phase is the peak in the sinusoid.

Examples

phasecalc(cosine=0, sine=1) # pi/2
