:Parameters:
- `arraylist` : Sequence
A list of (masked) arrays. Each element of the sequence is first converted
to a masked array if needed. If a 2D array is passed as argument, it is
processed line by line
- `dtype` : numeric.dtype
Data type descriptor.
- `shape` : Integer *[None]*
Number of records. If None, `shape` is defined from the shape of the first
array in the list.
