A vector is an array of numbers designed for high-performance computations. For a full list and details of functions and operators on vectors, see Vector Functions and Operators on Vectors. |
Vector basics
Vectors serve as a way to perform computations with diverse data types. For instance, arrays of values can be extracted as vectors from data types such as fieldset
, geopoints
, netcdf
, odb
and table
. Some of these types also allow their arrays to be set using vectors.

Z = f(X)
is equivalent to :
...
for
...
each
...
value
...
i
...
...
Zi
...
=

f(Xi)
...
Boolean operators such as >
or <=
produce 0 when the comparison fails, or 1 if it succeeds. Thus :

Z
...
=

X
...
>
...
0
gives a vector where all the values are either 1 or 0 depending on the corresponding values of the vector X being above 0 or not.
