X random integers between 1 and 25

hello, im trying to create code to give me X random integers (defined by dialog box) between 1 and 25. i have a working dialog box to give me the X but i cant get the randi function to give me what i need. any help is appreciated. thanks

randi command has the power to help you

did you wrote it in randi([1 25],[1 1]) ??

that seems to give me 1 random number between 1 and 25. I would like X random numbers without repeating any number. how would that look?

sorry, it seems the problem isnt with my random number generator, its with my dialog box.

prompt = {'Enter how many noise pixils (0 to 25) to add to the picture:'};

dlg_title = 'Noise Addition';

num_lines = 1;

defaultans = {'0'};

usernoise= inputdlg(prompt,dlg_title,num_lines,defaultans)

%create noise matrix

r =randperm(25,usernoise)

how can i get that to use the user input?

[Sean de Wolski]

usernoise = str2double(usernoise{1})

Usernoise is returned as a cell array containing strings.
