Question

I want to get the output removing only a single row and returning rest rows using matlab.
For eg: Consider a matrix

A = [1  1  1; 2  2  2; 3  3  3; 4  4  4]

For case1, I need to have a separate matrix where first matrix is displaying the desired rows and other matrix displays the rest rows.

like B=1 then output will be two matrix where first matrix will be

C = [1  1  1]

and another matrix will be

D = [2  2  2; 3  3  3; 4  4  4]

similarly in next case B=2

then

C = [2  2  2]
D = [1  1  1; 3  3  3; 4  4  4]

How to write a matlab program for such case?

Answer 1

Try this, given your definitions of A and B

C = A(B,:)
D = A(setdiff(1:size(A,1),B),:)

I expect you can easily wrap these up into a function.
