Matlab function return value

Question

I have one program that has function and the problem, return value, it has too many output. Like exempley: y = text the answer comes up ``` Error in text (line 2) if nargin == 0 Output argument "array" (and maybe others) not assigned during call to " C:\Users
ame\Documents\MATLAB	ext.m>text". ``` The program text.m reads a txt file that contains a couple of names and numbers like exemple: John doughlas 15986 Filip duch 357852 and so on. The program convert them to 15986 Doughlas John and so on. ``` function array = text(~) 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); ``` Is there anyway to fix the problem without starting over from scr…

Accepted Answer

You specify the function output argument in the definition, but you don't assign anything to it in the function body.

For example, in

```
function y = student(j)                                
```

your output is `y`. So you have to assign something to `y`.
