input prompt using variable name in matlab

To input a prompt using a variable name in MATLAB, you can use the function input() and concatenate the prompt string with the variable name. Here's an example:

main.m
% define a variable name
var_name = 'my_variable';

% ask for user input with a prompt that includes the variable name
user_input = input(['Enter a value for ' var_name ': ']);

% display the user's input
disp(['You entered ' num2str(user_input) ' for ' var_name]);
266 chars
9 lines

In this example, the input() function prompts the user to enter a value, and var_name is concatenated with the prompt string using the square bracket notation. The function num2str() is used to convert the user input to a string so that it can be displayed along with the variable name using disp().

Note that input() returns the user's input as a string by default, so you may need to convert it to a numeric value using str2num() or str2double() if you plan to use it in mathematical calculations.
