Reads a chunk of matrix data into a provided buffer. Multi-dimensional matrices are de-interleaved according to their natural dimensional ordering.

Reads a chunk of matrix data into a provided buffer.
Reads a chunk of matrix data into a provided buffer. If the stream-transposed
matrix has more than two dimensions, the de-interleaving is regularly from
from to back. E.g. in a matrix of shape [a][b][c], if a is the streaming
dimension, the first channel is b0, c0, the second channel is b0, c1,
and so on until b0, ck-1 where k is the size of third dimension, followed
by b1, c0 etc.
Note: Calls must not be mixed with calls to readDouble1 or readWindowDouble1D!

Reads a window (chunk) of matrix data into a provided buffer.
Reads a window (chunk) of matrix data into a provided buffer.
The window is a selection of dimensions, provided by the dims argument.
For each call, a successive window is read, where successive means iterating
over the remaining dimensions.
For example, if the input matrix has shape [time: 180][lon: 12][lat: 36][alt: 601],
then specifying dims = [0, 3] means that we get time-altitude windows, the first
window corresponding to lon = 0, lat = 0, the second window corresponding to
lon = 0, lat = 1, the 37th window corresponding to lon = 1, lat = 0, etc.
Note: Calls must not be mixed with calls to readFloat2D or readDouble1D!
Also in repeated calls, dims must not be changed.
