Operation between two fieldsets. op is one of the operators below :
+ Addition | - Subtraction |
* Multiplication | / Division |
^ Power |
|
The fieldsets returned by these boolean operators are boolean fieldsets (containing only 1 where result is true, 0 where it is false) :
> Larger Than | < Smaller Than |
>= Larger or Equal | <= Smaller or Equal |
= Equal | <> Not Equal |
In all of the above operations, a missing value in one of the input fieldsets results in a corresponding missing value in the output fieldset.

# copies fields 1, 5, 9, 13, 17 of x into y
Y = X[1,20,4]
fieldset fieldset[vector]
Extract a selection of elements from a vector. The vector supplied as the argument provides the set of indices to be used. For example:# copies fields 2, 1, 3 of x into y
x = |2, 1, 3|
y = x[i]
fieldset abs ( fieldset )
Returns the fieldset of the absolute value of the input fieldset at each grid point or spectral coefficient. Missing values are retained, unaltered by the calculation.
