Thank you )

hi,
I want to transform a matrix into a group (I work with EV6)
I tried the following syntax:
matrix (2,2) a
mtos (a,g1)

an error message appears.
please what can I do to correct this program?
thanks.

hi,
I have a vector v whith 100 observations;
please how can I form 4 vectors v1, v2, v3 and v4 when each one contains 25 observations and that satisfies v=(v1,v2,v3,v4)'.

hello,
I want to generate a 3 dimentional vector normally distributed with constant mean and variance <1.
Do I generate each element separately? and what parameters to assign to each element?
Thanks.

HELLO,
please how can I simulate a matrix with time varying coefficients.
for example, A(t)=A(t-1)+v(t) / v(t)~iidN(0,1)
I can simulate one coefficient of the matrix; for example a1:
smpl @all
series a1=0
smpl @first+1 @last
a1=a1(-1)+nrnd

my problem is how to simulate the matrix?
thanks a lot.
