say i have a matrix with things in it, and things are each column vectors 10000 in length,
data = [ thing1(:) thing2(:) thing3(:) thing4(:) ]
how can i manipulate data so that i can turn each of these things into separate outputs that are 100*100 in size
thanks

thing100x100 = rehape(thing1, [100, 100]); % Reshape 10,000 elements into 100x100

This should do the job if you have four column vectors:
data = [reshape(data(:,1),100,100) reshape(data(:,2),100,100)...
reshape(data(:,3),100,100) reshape(data(:,4),100,100)]
and each of those things would be, for example:
thing1 = reshape(data(:,1),100,100);
