Hi, I want translate matlab code in sas.

Below the matlab code:

where P is Probability vector.

I try whit proc iml.

Y= quantile('LOGNORMAL',b,&mu.,&sigma.)

but the resul is a singol number, I want a vector.

## Re: quantile function

Are you sure that your matrix b is a vector?  I tried the following and it seems to work for me.

proc iml;

p=do(0.50,0.95,0.05)`;

Y=quantile('LOGNORMAL',p,0,1);

print p Y;

quit;

this gives the following output:

0.5         1
0.55 1.1338981
0.6 1.2883304
0.65 1.4700854
0.7 1.6894457
0.75 1.9630311
0.8 2.3201254
0.85 2.8191443
0.9 3.6022245
0.95 5.1802516

## Re: quantile function

You are right.

There was an error in matrix b.

there wasn't a vector.

Thank you.
