Matrix indexing multiple rows

How can I select specific rows of a matrix. For example if I have a matrix with 10 rows and 3 columns. I want rows 2-4 and rows 5-8.

My matrix is actually has 1000 rows and 6 columns but if it can be done for a small matrix, then I can do it for a larger one.

Answer 1

[James Tursa]

x = your matrix
result = x([2:4,5:8],:);  % <-- pick off rows 2-4 and 5-8

Of course, the 2:4 and 5:8 could have been combined to just 2:8 for this example, but I assume you may have variables for the row numbers in your real problem.

Answer 2

x= matrix

q= [x(2:4,:) ; x(5:8,:)]
