Outer Product Operator ( o .) r;70
The symbols for the outerproduct 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: Ao .@B, whereais 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:
The above example is the same as doing the following for each element in the result:
