How do code for user input of text file name to be read?

I've been using:

fid=fopen('Doc.txt','r')

so far and have no clue how I'm meant to code for user input of file name which then reads the file.

I'm used to using :

evalresponse = input(promt)

but that's clearly not applicable here.

Also, how do you specify which characters to print to file and which to ignore? Last night I figured out how to create a program to output the number of vowels in a text file.

Now I need to get it to print to file the text document without any vowels and that seems a lot more complicated, at least to a beginner like me.

I've tried the 'type' handle but that just prints to file the entire text indiscriminately. Would really appreciate some help with this.

use uigetfile() to get the name

Use regexprep() to replace vowels and then print the file:

regexprep(str, '[aeiou]','*') % to replace with an asterisk

[baseFileName folder] = uigetfile();
fullFileName = fullfile(folder, baseFileName);
