I have P being a 17x1 cell, each cell representing a subject. Each of the 17 cells within P is a 3x1 cell, representing contrast images for each subject. So basically there are 17 subjects, 3 contrast images per subject. So to index the 3rd
contrast images of the 14th
subject, I would do P{14,1}{3,1}
. However, I would like to turn P into 3*17 x 1 cell (or 51x1 cell) instead. This means there are no nested cells within each cell in P. So P would be something like this:
Subject1/contrast1.img
Subject1/contrast2.img
Subject1/contrast3.img
Subject2/contrast1.img
Subject2/contrast2.img
Subject3/contrast3.img
...
Subject17/contrast3.img
Could anyone tell me how this may be accomplished?
How about a oneliner?
a = {{1;2};{3;4};{5;6};{7;8}}
b = vertcat(a{:})
