The program myfile.m reads a txt file that contains a total of 25 names and numbers like
exemple:
John doughlas 15986
Filip duch 357852
and so on.
The program converts them to
15986 Doughlas John
357852 duch Filip
This is without function, with it I get too many outputs.
Error message:
Error using disp
Too many output arguments.
Error in red4 (line 26)
array = disp(All);
Original code below:
function array = myfile(~)
if nargin == 0
dirr = '.';
end
answer = dir(dirr);
k=1;
while k <= length(answer)
if answer(k).isdir
answer(k)=[];
else
filename{k}=answer(k).name;
k=k+1;
end
end
chose=menu( 'choose file',filename);
namn = char(filename(chose));
fid = fopen(namn, 'r');
R = textscan(fid,'%s %s %s');
x=-1;
k=0;
while x <= 24
x = k + 1;
All = [R{3}{x},' ',R{1}{x},' ',R{2}{x}];
disp(All)
k = k + 1;
end
fclose(fid);
Now I have got many good answers from people and sites like functions but I cant get the results like the above with function.
I have tried combining them and got some results:
y = 15986 & [a,z,b] = myfile
y = 25 & myfile = x
y = numbers name1,2,3,4 and so one & myfile = fprintf(All)
y = & I used results().namn,
numbers name 1 & results().id, results().lastname
y =
numbers name 2 and so on.
The result I want is:
y = myfile
y =
15986 Doughlas John
357852 duch Filip
update: Change it like Eitan T said but did't get the result like above.
Got the result:
'John doughlas 15986'
'Filip duch 357852'
function C = myfile()
if nargin == 0
dirr = '.';
end
answer = dir(dirr);
k=1;
while k <= length(answer)
if answer(k).isdir
answer(k)=[];
else
filname{k}=answer(k).name;
k=k+1;
end
end
chose=menu( 'choose',filname);
name = char(filname(chose));
fid = fopen(name, 'r');
C = textscan(fid, '%s', 'delimiter', '');
C = regexprep(C{1}, '(\w+) (\w+) (\w+)', '$3 $2 $1');
fclose(fid);
Why use loops? Read the lines at once with textscan
and use regexprep
to manipulate the words:
fid = fopen(filename, 'r');
C = textscan(fid, '%s', 'delimiter', '');
C = regexprep(C{1}, '(\w+) (\w+) (\w+)', '$3 $2 $1')
fclose(fid);
The result is a cell array C
, each cell storing a line. For your example, you'll get a 2×1 cell array:
C =
'15986 doughlas John'
'357852 duch Filip'
I'm not sure what you want to do with it, but if you provide more details I can improve my answer further.
Hope this helps!
