评论： Simon Hammerlid 2019-10-4

I am writing a script that compares the temperature of two cities, and I want to be able to switch which cities I'm comparing without having to rewrite my code. Therefore I wrote the following code:

prompt = "What is the file address to the first city?"
firstcity = input(prompt, 's')
load firstcity

To which an answer could be: Cities/Paris.txt

Which would replace:

load Cities/Paris.txt

I'm not aware of a datatype for a fileadress, and am left unsure of how i would go about solving this problem.

在 MATLAB Online 中打开

You can use uigetfile command:

disp( "What is the file address to the first city?");
[firstcity,path] = uigetfile('*.txt');
if isequal(firstcity,0)
   disp('User selected Cancel');
else
   disp(['User selected ', fullfile(path,firstcity)]);
   load(fullfile(path,firstcity))
end
