Assign output a name?

Hi,

I am working on something where I have a vector of image files, and I get Matlab to shuffle them and give me one. I would like to take the output answer (the random image) and display it. How do I assign the output a name? I tried ans=RandImage, but that didn't work. Here's the code I have that leads up to this. Thanks!

Images = {'11a.bmp';'12b.bmp';'12c.bmp'; etc. etc.}

% Shuffle images

Images=Shuffle(Images)

Images{ceil(rand(1)*length(Images))}

%% Here's where Matlab gives me an image %%

ans = 11w.bmp

^ I would like to take this to somehow plug the output into the imread command.

Thanks!

Hi, for what I see, you need to do :

Images = {'11a.bmp';'12b.bmp';'12c.bmp'}; % list of images
RandomNumber = randi([1 length(Images)]); % random number between 1 and the number of images
image(imread(Images{RandomNumber)) % display the random image.

Thanks for your response! I've figured it out :)

just create an output variable.

Images = {'11a.bmp';'12b.bmp';'12c.bmp'; etc. etc.}

% Shuffle images

Images=Shuffle(Images)

MyRandomImage = Images{ceil(rand(1)*length(Images))};

then use

image(imread(MyRandomImage))

One Important thing : ans is a key word in matlab, try to never use it, otherwise you're gonna have some trouble later.
