rtfary
This command returns the array of force values used during the subsequent voltage or frequency sweep.
Usage
int rtfary(double *forceArray);
forceArray
Array of force values for voltage or frequency
Details
This command is used to return an array of voltage or frequency force values for a sweep. Send this
command before calling any sweep command.
To prevent a memory exception error, make sure that the array that will receive the sourced values is
large enough.
