ATAN overloads the atan operator for Analysis objects. Inverse tangent result in radians. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: ATAN overloads the atan operator for Analysis objects. Inverse tangent result in radians. ATAN(ao) is the arctangent of the elements of ao.data. CALL: ao_out = atan(ao_in); ao_out = atan(ao_in, pl); ao_out = atan(ao1, pl1, ao_vector, ao_matrix, pl2); POSSIBLE VALUES: ao_in = [ao2 ao3] ao_in = ao_vector ao_in = ao_matrix PARAMETER LIST: <key> <value> <description> tsdata fsdata xydata 'xdata' 't' 'f' 'x' compute the xdata 'ydata' 'x' 'xx' 'y' compute the ydata The following call returns a parameter list object that contains the default parameter values: >> pl = atan(ao, 'Params') HISTORY: 07-05-2007 Diepholz Creation %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
