get column names in SAS/IML

[ryankey]

HI, I got a matrix. Each column has its own name. How to get the names of the columns and save them into a vector?

for example, how to get the column names in the following matrix?

		proc iml;
		n = {1 2 3, 4 5 6};      /* 2 x 3 numeric */
		c = {'a' 'b', 'c' 'd'};  /* 2 x 2 character */

		nNames = "n1":"n3";
		cNames = "c1":"c2";
		create ndat from n[colname=nNames];
		append from n;
		create cdat from c[colname=cNames];
		append from c;

quit;

Many thanks!

Sincerely,

Ryan

Got it. Use CONTENTS function.
