Power Operator, Elementwise: ##

raises each element to a power

matrix1##matrix2

matrix##scalar

The elementwise power operator (##) creates a new matrix with elements that are the elements of matrix1 raised to the power of the corresponding element of matrix2. If any value in matrix1 is negative, the corresponding element in matrix2 must be an integer.

In addition to handling conformable matrices, the elementwise power operator allows either operand to be a scalar. In this case, the operation takes the power for each element and the scalar value. Missing values are propagated if they occur.

For example, the statements

   a={1 2 3};
   b=a##3;

result in

              B            1 row      2 cols     (numeric)

                                1         8       27

The statement

   b=a##.5;

results in

               B             1 row       3 cols    (numeric)
