How to perform matrix vectorization in PROC IML?

I would like to find vec(C). for example: 

C=  [1     2
     3     4]

vec(C)` = [1      3      2      4]

Take a look at the documentation for the SHAPECOL and SHAPE functions.   For example:

 

proc iml;
c = {1 2,
     3 4};
d = shapecol(c, 1, 4);
print d;

Thanks, 

I found another way which also works:

vec_c= colvec(c`);
print vec_c;
