Dear all,
I have a folder containing 8 images and I want matlab to choose only one of those images by random to display the picture in the center of the screen. The images are in the folder /congruent and are named for example "1.bmp" or "2.bmp".
I tried the follwing code, but it doesn't work as I don't really know how to access the images in the right way.
Thank you very much in advance!!
if trialcondition == 1 % congruent condition
randomnumber = randi([1 8]);
picture = imread(fullfile(pwd,'congruent',randomnumber,'*.bmp'));
elseif trialcondition == 2 % incongruent condition
% here should essentially happen the same but with a different folder

You could read all the images into a cell array (each image in an element), then:
for k=1:8
