- get input (either from the user or from another function)
- validate input (parse the input and check if it is correct, throw an error if it isn't)
- do actual calculations
- prepare results for output (may depend on input, depending on your function)
Making a nice and small 'Loding Data' Script

Hey,
I am currently trying to write a script that should be at the beginning of a larger one.
The user would run the script and be asked by the program:
-Where is the file ?
-Filename?
-other (for later)?
The script should then load the requested file into Matlab. It is measurement data in a .txt file.
I searched a lot and tried it like this:
But it doesn't work as hoped
box = msgbox('Hello, blablabla');
%set(box, 'position', [500 500 200 100]);
pause(1.2)
Folder = uigetdir();
Folder_string=string(Folder);
prompt = {'Filename:','other:'};
dlgtitle = 'blablabla';
%size of the window
width = 75;
height = 1;
dims = [height, width];
definput = {'Filename','other'};
answer = inputdlg(prompt,dlgtitle,dims,definput);
Dataname=string(answer(1,1));
other=string(answer(2,1));
%% Import
% Use Var: 'Dataname' and 'Folder' for Import:
Data = load(fullfile(Folder_string,Dataname));
After choosing the path an the filename an error appears. :(
"Error using load Number of columns on line 3 of ASCII f
ile C: \ bla \ bla \ bla \ bla \ bla \ filename must be the same as previous lines.
Error in dialog (line 45) Data = load (fullfile (Folder_s, Dataname));"
Now i dont know what to do......

That looks like a very strange file. It looks like 3 files were merged.
You can select the lines you're interested in like this:
file_contents=fileread('SBA15_Data.txt.txt');
file_contents=strsplit(file_contents,'\n');
file_contents=file_contents(6:605);
Then you only need to parse them to numeric values.

The code below should read your file and convert it to a double array.
file_contents=fileread('SBA15_Data.txt.txt');
file_contents=strsplit(file_contents,'\n');
file_contents=file_contents(6:605);
parse_val=@(str) cellfun(@str2double,strsplit(strtrim(str),' '));
x=reshape(file_contents,[],1);
x=cellfun(parse_val,x,'UniformOutput',false);
x=cell2mat(x);
