+ − % DESCRIPTION: CONVERT perform various conversions on the ao.
+ − %
+ − % CALL: ao = convert(ao, pl)
+ − %
+ − % PARAMETERS:
+ − %
+ − % 'action' - choose a conversion to make [default: none]
+ − %
+ − % Possible actions:
+ − %
+ − % Unit conversions:
+ − % 's to Hz' - convert seconds to Hz in the yunits of this AO.
+ − % 'Hz to s' - convert Hz to seconds in the yunits of this AO.
+ − %
+ − % Data conversions:
+ − % 'to cdata' - convert the data in the AO to a cdata type.
+ − % 'to tsdata' - convert the data in the AO to a tsdata type.
+ − % 'to fsdata' - convert the data in the AO to a fsdata type.
+ − % 'to xydata' - convert the data in the AO to a xydata type.
