- Placeholder functions are used. You will need to define these based on the mathematical expressions provided in your image.
- The script assumes ln represents the natural logarithm (base e). In MATLAB, this is log.
- The u function is calculated for a range of x values and for each value of alpha in the array alphas.
- The arrayfun function is used to evaluate u for each element in the x array.

Given the complexity of these functions, setting up the entire system in MATLAB is quite involved. However, I can demonstrate the basic approach with placeholder functions. You will need to replace these with the actual implementations of your functions.
% Define the functions B1, B2, Delta, Delta1, Delta2, Dk, and W
B1 = @(x, s, a) sin((a*x + b)/(a*x + b)) / ((a*x + b)/a + sqrt(1 + s*a));
% ... Define B2, Delta, Delta1, Delta2, Dk, W in a similar manner
% Constants given in your problem
f1 = 0.5;
f2 = 3;
c = 0.1;
d = 2;
% Calculate Delta for the given constants
Delta = @(s, a) B1(c, s, a) * B2(d, s, a); % Replace with the actual function
% Define u(x, t)
u = @(x, t, a) ln(2)/t * W; % W needs to be calculated using the given sum
% Example: Plot u(x, t) for a fixed t and range of x for different values of alpha
t = 0.5;
x = linspace(0, 10, 100); % Define a range of x values
alphas = [0.1, 0.5, 1.0]; % Example values of alpha
% Plot u(x, t) for each alpha
figure;
hold on;
for alpha = alphas
y = arrayfun(@(x_val) u(x_val, t, alpha), x);
plot(x, y, 'DisplayName', sprintf('alpha = %f', alpha));
end
hold off;
legend;
xlabel('x');
ylabel('u(x, t)');
title('Plot of u(x, t) for different values of alpha');
Replace the placeholder functions with the actual implementations of your mathematical expressions and adjust the range of x and the array alphas as needed for your specific requirements.
