pupilsizeangle

The pupilsizeangle function returns the angle dependend apparent pupil size factor, based on the values provided by Wyszecki & Stiles, see reference.

Usage:

 A = pupilsizeangle(tilt_angle,interp_method)

Where:

Parameter	Description
A	Returns the corrsponding appearent pupil size factor, scalar or vector.
tilt_angle	Defines the tilt angle(s), scalar or vector.
interp_method	Defines the interpolation method, default: linear

Example:

Plot appearant pupil size factor depending on tilt angle:

t = 0:90;
a = pupilsizeangle(t);

plot(t,a)
grid on
xlabel('Tilt angle in degree')
ylabel('Apparent pupil size factor')

Result:
