Focus Processing Options
Specify what operation should be performed on the selected goal.
The following processing steps are common to all goals.
- No processing
- Where the focus is non-complex, no processing steps are required. In order to
consider the focus directly, the No processing option is
provided.
(1) - Real/Imaginary/Magnitude/Phase
- Selects a specific component of a complex focus type. For an array, the complex
component of each array element is taken, delivering a non-complex
array.
(2) - Unwrap
- Unwraps a phase component. For a phase array, the whole array is considered in
the unwrap process. This operator is applied directly after selecting
Phase.
(3) - Absolute value
- Takes the absolute value. For an array, the absolute value of each element is
taken.
(4) - Average/Minimum/Maximum
- Finds the average, minimum or maximum value of an array. This has no effect on a
single value.
(5) - Normalise
- Normalises to the largest value in an array. For a single value, “1” will
be returned.
(6) - Log
- Takes the base-10 logarithm. For an array, the base-10 logarithm of each element
of the array is taken. This operator is only available for non-complex values or
arrays.
(7) - Offset
- Adds a specified non-complex value. For an array, the value is added to each
element of the array. This operator is only available for non-complex values or
arrays.
(8) - Scale
- Multiplies by a specified scale factor. For an array, each element of the array
is multiplied by the scaling factor.
(9) - Exponent
- Applies an exponent. For an array of values, the exponent of each value in the
array is taken.
(10) - Undefined
- When a processing step is modified and the step becomes invalid, the processing step reverts to an Undefined state. Delete or redefine all Undefined steps before applying the changes to the goal.
