Section: Array Generation and Manipulations
arrayfun function is used to apply a function handle
to each element of an input array (or arrays), and to collect
the outputs into an array. The general syntax for its use is
y = arrayfun(fun, x)
where x is an N-dimensional array. In this case, each
element of the output y_i is defined as fun(x_i). You can
also supply multiple arguments to arrayfun, provided all of the
arguments are the same size
y = arrayfun(fun, x, z,...)
in which case each output y_i = fun(x_i,z_i,...).
If the function returns multiple outputs, then arrayfun can be
called with multiple outputs, in which case each output goes to
a separate array output
[y1,y2,...] = arrayfun(fun, x, z, ...)
The assumption is that the output types for each call to fun is
the same across the inputs.
Finally, some hints can be provided to arrayfun using the syntax
[y1,y2,...] = arrayfun(fun, x, z, ..., 'param', value, 'param', value)
where param and value take on the following possible values:
'UniformOutput' - if the value is true then each output of fun
must be a scalar, and the outputs are concatenated into an array the same size
as the input arrays. If the value is false then the outputs are encapsulated
into a cell array, with each entry in the cell array containing the call to
fun(x_i,z_i,...).
'ErrorHandler' - in this case value is a function handle that gets called
when fun throws an error. If 'ErrorHandler' is not specified, then arrayfun
allows the error to propogate (i.e., and exception is thrown).
