%GENERATEMULTICOLORTEXT Generates a multicolored text string for MATLAB text objects.
%
% chars = GenerateMultiColorText(textCell)
% chars = GenerateMultiColorText(textCell, colors)
%
% This function creates a concatenated text string where each segment is displayed
% in a different color. It is intended for use with MATLAB text objects that support
% the 'Interpreter' property set to 'tex'.
%
% INPUTS:
% textCell - Cell array of strings or character vectors. Each element is a text segment
% to be colored separately.
% Example: {'Hello', 'World', '!'} or {"Hello", "World", "!"}
%
% colors - (Optional) An N-by-3 matrix of RGB color values, where N is the number of text segments.
% Each row corresponds to the color of the respective text segment in 'textCell'.
% RGB values should be in the range [0, 1].
% If 'colors' is not provided or is empty, the function generates equidistant colors.
%
% OUTPUT:
% chars - A formatted string combining all text segments with their specified colors.
% This string can be used with text objects by setting 'Interpreter' to 'tex'.
%
% OPTIONS:
% The function requires the text object to have the 'Interpreter' property set to 'tex'.
% Ensure you specify this property when displaying the text.
%
% EXAMPLE:
% % Define text segments
% textCell = {'Hello, ', 'World', '!'};
%
% % Define colors for each segment (optional)
% colors = [1, 0, 0; % Red
% 0, 1, 0; % Green
% 0, 0, 1]; % Blue
%
% % Generate the multicolored text string
% chars = GenerateMultiColorText(textCell, colors);
%
% % Display the text in a figure
% figure;
% text(0.5, 0.5, chars, 'Interpreter', 'tex', 'FontSize', 14, 'HorizontalAlignment', 'center');
% axis off;
%
% SEE ALSO:
% text, annotation, sprintf
%
% NOTE:
% - The function assumes that 'textCell' is provided as a cell array of strings or character vectors.
% - The 'colors' matrix must have the same number of rows as the number of text segments.
% - RGB values in 'colors' should be between 0 and 1.
% - The function utilizes MATLAB's TeX interpreter for coloring text.
