Read strings from a text file and pass it to variables

I have this code in matlab that seems to read the content of my file

fid = fopen('file.txt');

tline = fgets(fid); while ischar(tline) disp(tline) tline = fgets(fid);

end

fclose(fid);

what I have Included in the file are inputs. they are align in the file in that format

20

40

30

30

Is there a way to grab them one by one and assign them to a variable that is

part of a function such as function [lala]=myfunc(t,k,l,m)

Answer 1

[TAB]

fid = fopen('file.txt');

% Read all lines & collect in cell array
txt = textscan(fid,'%s','delimiter','\n'); 

% Convert string to numerical value
Val = str2double(txt{1}); 
t = Val(1);
k = Val(2);
l = Val(3);
m = Val(4);

% Call your function
[lala]=myfunc(t,k,l,m);

A = fscanf(fid, '%g', Inf);
fclose(fid);
