1 % ASIN overloads the asin method for analysis objects.

4 % DESCRIPTION: ASIN overloads the asin operator for analysis objects.
5 % Inverse sine result in radians.
6 % ASIN(ao) is the arcsine of the elements of ao.data.
7 %
8 % CALL: ao_out = asin(ao_in);
9 % ao_out = asin(ao_in, pl);
10 % ao_out = asin(ao1, pl1, ao_vector, ao_matrix, pl2);
