Dear All:
I am trying to run a simple live script:
%mesh
x1=linspace(-pi, pi, 20);
x2=linspace(-10, 10, 30);
%Call meshgrid to create a cartesian
[X1, X2]=meshgrid(x1, x2);
%Evaluate the function at these (X1, X2) pairs
Z = cos(X1).*X2;
figure
mesh(X1, X2, Z)
In the beginning, clicking 'Run Section' will run the code correctly. At that time, the script has not been saved yet. So the script's name was 'untitled.mlx'. Then I saved the script as 'mesh.mlx'. Now, clicking 'Run Section' has the red error: Attempt to execute a SCRIPT mesh as a function: /MATLAB Drive/mesh
Why no error before the live script was saved and error afterwards? My screenshot is attached.
Thank you very much for your help. I greatly appreciate it.

Because your live script has the same name than the function mesh and when you call this function, in fact you are calling your live script. -> Change the name of your script

Thank you very much for your help. I see. Now I have renamed the file 'mesh.mlx' to 'my_mesh.mlx' and it has worked.
I greatly appreciate your help. Have a nice day!
