I can't get the area to fill between the dimensions quite right, it keeps shaping wrong area, so far i have this code below
closeclearclcr_d = 1.50e11; % distance from Earth to Sun
r_s = (1.39e9)/2; % radius of the sun
fw =(r_s/r_d)^2;t_s = 5800; % temp in kelvin
h = 6.626e-34; % in J*s
k_b = 1.381e-23; % in J/K
c = 2.998e8; % in m/s
syms lambda L_sunlambda = (0.001:0.01:3)*1e-6;L_sun = fw .* (2*pi*h*c.^2) ./ lambda.^5 .*... 1./(exp((h*c)./(lambda*k_b*t_s)) -1);figure(1)plot(lambda, L_sun, 'b-', 'LineWidth', 2);xlim([0 3e-6]);xlabel('Wavelength (um)');ylabel('Spectral Irradiance (W*m^2/m^-1)');legend('L_s_u_n')set(gcf, 'PaperPositionMode', 'manual');set(gcf, 'PaperUnits', 'inches');set(gcf, 'PaperPosition', [0 0 6.75 5]);print('SolarIrradiance.tif', '-dpng', '-r600')saveas(gcf, 'SolarIrradiance.fig')%%
% Part 2.
maxL_sun = max(L_sun);lambda_max = lambda(51);% i. this falls in the visible region
% ii. uv = 6.4%, vis = 48%, and ir = 45.6%
% the energy for uv = 87, vis = 565, and ir = 623
UV = L_sun(1:38);Vis = L_sun(39:78);IR = L_sun(79:300);UV_Vis_IR_fig = openfig('SolarIrradiance.fig');hold on
and i need to shade the UV, Vis, and IR regions of a previously made graph and save it as a new one
