please help me in my project

hi,can any one help me to generate non Gaussian noise with any distribution?
and if i have tow term Gaussian mixture model with probability distribution as
f=(1-epselon)N(0,v^2)+epsilon*N(0,k*V^2)
where
v > 0
0<epsilon<1
0<k
thank you for your attention

Do you need matlab code?

thank you joebazoka for your attention ........
i know that to simulate noise with guassin distribution with zero mean and unite variance i use randn matlab command to do this as
noise=randn(1,100);
and to change noise mean and var ,i use..
noise=new_mean+sqrt(new_var)*randn(1,100);
then how can i simulat mixture guassin noise if it have pdf as ....
f=(1-epselon)N(0,v^2)+epsilon*N(0,k*V^2)
where
v > 0
0<epsilon<1
0<k
i think to simulate it as
since the pdf have zero mean
noise=(1-epselon)*sqrt(v)*randn(1,100)+epsilon*sqrt(k*v)*randn(1,100);
is this ok or wrong
thanks again for you help
