ask for the filename in matlab

To ask for the filename in MATLAB, you can use the input() function to prompt the user for input. Here is an example:

main.m
filename = input('Enter the filename: ', 's');
47 chars
2 lines

In this example, input('Enter the filename: ') displays the message "Enter the filename: " in the command window, and the user can enter the filename after the prompt. The 's' argument in input() specifies that the input should be treated as a string.

After running the code, the entered filename will be stored in the variable filename, and you can use it further in your MATLAB program.
