How to choose image

Hi all,

I'm initially randomly choosing two images from a folder (both with different specifications) and then I want to randomly display one on the left and one on the right. However, I don't know how to do the randomization before selecting them for either left or right.

Do not store them in two separate variables, but use a cell or struct array! It is the contents of variable that should vary, not the name ...

img{1} = imread( i1 );
img{2} = imread( i2 );
%drawing it on the back buffer

X = randperm(2) % [1 2] in random order 
myTexture = Screen( 'MakeTexture', window, img{X(1)} );  
Screen( 'DrawTexture', window, myTexture, [], rectL );
myTexture2 = Screen( 'MakeTexture', window, img{X(2)} );
Screen( 'DrawTexture', window, myTexture2, [], rectR );
