Making an app that can edit functions

6 次查看(过去 30 天)
Hello I have a GUI that sets the inputs for a long script that uses one specific function to set a value based on different decision making steps. I would like the user to be able to write the code for one of these decision making processes within the GUI and then have that user's written code added to my function. Is there a way of having a GUI rewrite functions for a script like this?

Hi Antonio,
I understand that you are looking for a way to incorporate user-entered code into your function for decision-making purposes.
To do this, you can use the “eval function in MATLAB. The eval function allows you to execute MATLAB code that is provided as a string. By passing the text entered by the user from the GUI as input to the eval function, you can execute the code within your function.
Here is an example of how you can use the eval function:
% Assume userCode is the string containing the user-entered code
userCode = 'disp("Hello, world!");';
% Use eval to execute the user's code
eval(userCode);
In this example, the userCode variable holds the code entered by the user as a string. By using eval, the code is executed, and the output, in this case, would be the display of "Hello, world!".
However, it is important to note that using eval with user-entered code can be risky, as it can introduce security vulnerabilities and make your code harder to debug. It is generally recommended to use eval with caution and validate any user-provided input or code to ensure its safety and reliability.
For more information on the eval function, please refer to the following MATLAB documentation: https://www.mathworks.com/help/matlab/ref/eval.html
Additionally, the below documentation also provides alternatives to using eval, which you may find helpful: https://www.mathworks.com/help/matlab/matlab_prog/string-evaluation.html
Hope this Helps!
