### 2.2 Function pararrayfun

Function File: [o1, o2, …] = pararrayfun (nproc, fun, a1, a2, …) ¶
Function File: pararrayfun (nproc, fun, …, "UniformOutput", val) ¶
Function File: pararrayfun (nproc, fun, …, "ErrorHandler", errfunc) ¶

  Evaluates a function for corresponding elements of an array. Argument and options handling is analogical to `parcellfun`, 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 fun is able to operate on vectors rather than just scalars, and returns a vector. The same must be true for errfunc, if given. In this case, the array is split into chunks which are then directly served to func for evaluation, and the results are concatenated to output arrays. If "CumFunc" is also specified (see `parcellfun`), fun is expected to return the result of the same cumulative operation instead of vectors.
