<dd><p>Evaluates a function for corresponding elements of an array.
Argument and options handling is analogical to <code>parcellfun</code>, except that
arguments are arrays rather than cells. If cells occur as arguments, they are treated
as arrays of singleton cells.
Arrayfun supports one extra option compared to parcellfun: "Vectorized".
This option must be given together with "ChunksPerProc" and it indicates
that <var>fun</var> is able to operate on vectors rather than just scalars, and returns
a vector. The same must be true for <var>errfunc</var>, if given.
In this case, the array is split into chunks which are then directly served to <var>func</var>
for evaluation, and the results are concatenated to output arrays.
If "CumFunc" is also specified (see <code>parcellfun</code>), <var>fun</var> is
expected to return the result of the same cumulative operation
instead of vectors.
