extracting values from a matrix
显示 更早的评论
Hey,
I have a matrix for my latin squared design which randomised my conditions across my sentence stimuli. Is it possible to extract specific values from a matrix and sort them into groups?
E.g. I want to extract from my matrix the values 1, 2 and 3 and group them into an array called block 1
(then the same again for the values 4, 5, and 6 and group those into block 2
Thanks!!

It's not clear what you are trying to do. Try providing more detail, such as an example of the matrix and an example of the arrays (block1, block2) you are trying create from the matrix.

If M is your matrix, then block1 below will be a vector with all elements of M with value equal to 1, 2 or 3, in the order they are in M
block1 = M(M >= 1 & M <= 3);
