### Constracting two matrices with odd and even rows

Posted:

**Wed Oct 23, 2013 7:37 am**I have a matrix with 100 rows and 100 column: M(100,100).

I need to construct two matrices one with the odd rows and with the even rows: M_odd(50,50 and M_even(50,50)

I have extracted the raws using the following loop

for !i =1 to 100

rowvector r!i = @rowextract(M,!i)

next

EVEN rows

rowplace(M_even,r1,1)

rowplace(M_even,r3,2)

etc...

ODD rows

rowplace(M_odd,r2,1)

rowplace(M_odd,r4,2)

etc...

**How can I construct the two matrices with a loop in order to avoid to following manual approach?**EVEN rows

rowplace(M_even,r1,1)

rowplace(M_even,r3,2)

etc...

ODD rows

rowplace(M_odd,r2,1)

rowplace(M_odd,r4,2)

etc...
