Hi,
It looks like you are encountering an error in MATLAB related to an undefined function or variable named untitled. Following article by MathWorks Support Team could be helpful:
As stated in the article, MATLAB does not recognize the specified string as the name of a function on the MATLAB path or as a variable. The error can be caused by:
- Trying to use a variable that has not been defined before this line of code executes.
- A typographical error when typing a function or variable name.
To resolve, ensure that the function untitled is defined in your MATLAB path. You should have a file named untitled.m that contains the function definition. If the function untitled is defined within a script or another function, ensure that it is within the scope and accessible where you're trying to call it.
I hope the information provided above is helpful.
