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:

Add two Numeric Edit Field components for the inputs.
Add a Button component to trigger the calculation.
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:

You can also refer to this documentation to know more about how to create a simple app:

Hope this helps you in moving forward

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.

If you would like to learn more about App Designer, you might find the following MathWorks Onramp course helpful:
