+ Note on architecture
+======================
+
+There are three sets of parameters relevant for reading files. The
+first are *file read parameters* - containing options that are common
+for reading the whole file, and therefore every variable within that
+file. At the moment these are:
+
+* mat_stream
+* dtypes (derived from byte code)
+* byte_order
+* chars_as_strings
+* squeeze_me
+* struct_as_record (MATLAB 5 files)
+* class_dtypes (derived from order code, MATLAB 5 files)
+* codecs (MATLAB 5 files)
+* uint16_codec (MATLAB 5 files)
+
+Another set of parameters are those that apply only to the current
+variable being read - the *header*:
+
+* header related variables (different for v4 and v5 mat files)
+* is_complex
+* mclass
+* var_stream
+
+With the header, we need ``next_position`` to tell us where the next
+variable in the stream is.
+
+Then, for each element in a matrix, there can be *element read
+parameters*. An element is, for example, one element in a MATLAB cell
+array. At the moment, these are:
+
+* mat_dtype
+
+The file-reading object contains the *file read parameters*. The
+*header* is passed around as a data object, or may be read and discarded
+in a single function. The *element read parameters* - the mat_dtype in
+this instance, is passed into a general post-processing function - see
+``mio_utils`` for details.

+

+    -----
+    We had to decide what shape a 1 dimensional array would be by

+    default for a vector in MATLAB (e.g., ``>> 1:12``) is a row vector.
+
+    Versions of scipy up to and including 0.11 resulted (accidentally)
+    in 1-D arrays being read as column vectors. For the moment, we
+    maintain the same tradition here.
+
+    Examples
+    --------
+    >>> import numpy as np
+    >>> from scipy.io.matlab._miobase import matdims
+    >>> matdims(np.array(1)) # NumPy scalar

+    (2, 1)
+    >>> matdims(np.array([[2],[3]])) # 2-D array, column vector
+    (2, 1)
+    >>> matdims(np.array([[2,3]])) # 2-D array, row vector
+    (1, 2)
+    >>> matdims(np.array([[[2,3]]])) # 3-D array, rowish vector
+    (1, 1, 2)
+    >>> matdims(np.array([])) # empty 1-D array
