I am trying to generate a random number from a mixture normal distribution but got an error message that the matrices do not conform to the operation. Here is my code:

proc iml;

call randseed(12345);

p = {0.2 0.5 0.3};  mu = {0 5 10}; sig = {1 1 2};

call randgen(x, 'NORMALMIX',p,mu,sig);

print x;

quit;

The NORMALIMIX family was added in SAS/IML 12.1, which shipped with SAS 9.3m2.
