I currently have a 1024x1024 array. I want to find the first and fourth quartile range for this array. (I already used iqr(a(:)) to find the interquartile range, however now I want to find the first and fourth). Thank you!

You can use 'prctile' on the flattened array to calculate the 25th percentile which in turn will give you the first quartile.
a = rand(1024,1024);
a_flattened = a(:);
out = prctile(a_flattened,25)
You can refer to the documentation page of 'prctile' for more information on the same by executing the following command from MATLAB command window.
doc prctile
Thanks!
