Outer Product Operator (0 .) CD 0
The symbols for the outer product operator are 0 •• The outer product operator
causes a specified primitive scalar dyadic function to be applied between argument A
and argument B so that every element of argument A is evaluated against every ele-
ment of argument B. The form of the function is: A 0 .CDB, whereG)is a dyadic
primitive scalar function. Arguments A and B can be any expressions. Unless
argument A is a scalar, the shape of the result is the shape of argument A catenated
to the shape of argument B. If argument A is a scalar, the shape of the result is the
same as the shape of argument B:
