Retrieving data from txt file.

%I retrieve data from excel like that,

[FileName1,PathName] = uigetfile('*.xlsx','Select the excel file')
[num,txt1,raw] = xlsread(FileName1)

%I have a .txt file which I need to extract data from it so I need to apply this way to retrieve data from a .txt file. How can I do that.

[FileName1,PathName] = uigetfile('*.xlsx','Select the excel file')
[num,txt1,raw] = xlsread(fullfile(PathName,FileName1))

For a text file you cane use importdata

[sermet]

I need to read txt file not xlsx file.

[Azzi Abdelmalek]

For txt file, you need to know the format of your data in your txt file. Can you post a sample of your data?

[sermet]

points_id x y z

A 100 150 200

B 200 300 400

I want that users can choose the txt file and retrieve data from it like in my above example (xlsread)

[sermet]

I need to classify num, txt1, raw like above example

[Azzi Abdelmalek]

fid=fopen('file.txt') 
a=textscan(fid,'%s %f %f %f','headerlines',2)
fclose(fid)
text1=a{1}
num=cell2mat(a(2:4))
