paint a sunset in matlab

To paint a sunset in Matlab, we first need to create a gradient of colors that represents the different hues of the sunset. We can use the linspace function to generate a range of values and then use the interp1 to obtain the corresponding color values. We can then create an empty image with the zeros function and fill it with the gradient of colors using the image function. Finally, we can adjust the colormap to enhance the visualization of the sunset.

main.m
% Define the range of colors for the sunset
c = [1 0 0; 1 0.5 0; 1 1 0; 1 1 1; 0 0.5 1; 0 0 1];

% Generate the corresponding color values
x = linspace(0,1,size(c,1));
xi = linspace(0,1,256);
colors = interp1(x,c,xi);

% Create an empty image
img = zeros(256,256,3);

% Fill the image with the gradient of colors
for i = 1:size(img,1)
    img(i,:,:) = colors(i,:);
end

% Adjust the colormap
colormap(colors);

% Visualize the sunset
image(img);
axis off;

This code will create an image that represents a sunset with a gradient of colors ranging from red to blue. You can adjust the values of the color map c to obtain different hues of the sunset, or modify the code to obtain a more realistic representation of a sunset.
