| Understanding the SAS/IML Language |
To specify a matrix literal with multiple elements, enclose the elements in braces. Use commas to separate the rows of a matrix. For example, the following statements assign and print matrices of various dimensions:
x = {1 . 3 4 5 6}; /* 1 x 6 row vector */
y = {1,2,3,4}; /* 4 x 1 column vector */
z = 3#y; /* 3 times the vector y */
w = {1 2, 3 4, 5 6}; /* 3 x 2 matrix */
print x, y z w;
