how to sort a matrix
显示 更早的评论
hi I have a big matrix A = [k x 1] where k is around 10,000 and k ranges from, say, a to b
i need get a matrix B from A for all the values of k ranging from a to c, where a < c < b;
I've tried everything by can't figure out how to do it.
Thanks,
B.

eg
a = 12
b = 125
A = randi([a b],20,1)
c = (a + b)/2;
B = A(A < c)
