v3.2.0

• A new wavefront error method has been added which accepts input coordinate vectors and a corresponding phase map;
• The more efficient method of evalpoly is now used to evaluate the radial polynomials;
• The shading / lighting is now turned off for the plots in order to improve the display.

Full Changelog: v3.1.0...v3.2.0

v3.1.0

v3.0.0

• Fitting to specific polynomials instead of the full range is now allowed using an input vector of (m, n) tuples containing the subset;
• Implemented a wavefront error matrix input method;
• The Model methods are now dispatched using parametric type selectors;
• The scale keyword option has been renamed to finesse;
• The new stack function is now used to efficiently construct the phase error fitting matrix;
• Slightly optimized the radial polynomial coefficient algorithm;
• Fixed conversion and indexing errors for wavefront error fitting under n_max = 0 (mean piston output);
• Log transforms are now constructed more efficiently using broadcasted assignment;
• Adjusted the allowed input types for the wavefront error modelling;
• The window and plot title keyword arguments are now optional;

• Log transforms of the Zernike polynomials are now plotted for high orders;
• Various improvements and optimizations.

v1.0.0

• Generation of Zernike polynomials;
• Fitting of wavefront errors;
• Aperture scaling algorithm based on Janssen & Dirksen (2007);
• Radial polynomial coefficient algorithm based on Honarvar & Paramesran (2013).
