Assigning file name as variable name

Hi everyone,
I would like to write a program. The program must ask users to enter the name of the text we're importing and change the variable name each time. The code I wrote is below:
name = input('Enter the name of a file: ','s');
s=importdata('name.txt');
data=s.data
t_name=data(:,1);
mass_name=data(:,4);
dtg_name=data(:,7);
[ax,p1,p2]=plotyy(t_name,mass_name, t_name,dtg_name,'plot','plot')
I have mainly 2 problems. Importing file from the code generated by input command and assigning t_name, dtg_name etc. variables each time. How can I fix it?
Thank you for your help

Try this:
% Have user browse for a file, from a specified "starting folder."
% For convenience in browsing, set a starting folder from which to browse.
startingFolder = 'C:\Program Files\MATLAB';
if ~exist(startingFolder, 'dir')
% If that folder doesn't exist, just start in the current folder.
startingFolder = pwd;
end
% Get the name of the file that the user wants to use.
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uigetfile(defaultFileName, 'Select a file');
if baseFileName == 0
% User clicked the Cancel button.
return;
end
fullFileName = fullfile(folder, baseFileName)
s=importdata(fullFileName);

If the importdata() is not working with your data, then you can try another input option like csvread(), textscan(), or whatever, or else write your own custom reading function.

Hi,
you should use name as a variablename to importdata:
name = input('Enter the name of a file: ','s');
s=importdata(name);
