¿How can I transform an already working code to a GUI?

I have a code that works fine and gives me the expected outputs. I don´t know how to transform that code into an app that asks me for the inputs and returns the plot of such result.

Hello Jose,

I think there isn't a fully automated way to convert MATLAB code directly into an app, but MATLAB App Designer provides a straightforward environment to manually create an app that leverages your existing code.

For example, if you have a MATLAB function that takes two inputs and generates a plot:

function myFunction(input1, input2)
    x = linspace(-10, 10, 100);
    y = input1 * x + input2;
    plot(x, y);
    title('Result Plot');
    xlabel('X-axis');
    ylabel('Y-axis');
end

In App Designer, you can use some components and add callbacks which call your function:

1. Add two Numeric Edit Field components for the inputs.
2. Add a Button component to trigger the calculation.
3. Add an Axes component to display the plot.

To learn how to call a function from within a callback, you can refer to these similar MATLAB Answers:

Hi @José Felipe Serna,

I understand that you want to create an app that follows the desired workflow. I would recommend utilizing the MATLAB App Designer feature for your use case.
