      Then it should just be to generate the gray-level (or separate R, G and B level) mappings that take you from 0-1 to 0-1.
qdSolarize = @(Igray) (1-0.7*sin((0.2+linspace(0,0.8,1001)*pi)).^8)
Isolarized = qdSolarize(I);
You'd have to fidget around with the mapping till you get whatever you want.
HTH.

        FWIW, MIMT has a solarization tool that has presets for both a smooth curve and a typical hard vee curve.  It also supports arbitrary curve specification.
A = imread('trailer.jpg'); % a photo (RGB)
B = solarize(A); % default curve
C = solarize(A,'vee'); % hard vee curve
D = solarize(A,'in',[0 0.10 0.70 0.94 1],'out',[0 0.10 0.90 0.08 0]); % custom
% show all of them
outpict = [A; B; C; D];
imshow(outpict)
