movstd's function-argument surface is incompatible with that of matlab.
Matlab does have an argument called weight, while octave does not.

This leads to incompatibilities like the following:

result = movstd(inputData, windowWidth, 0, 2);

This works in Matlab. The 0 specifies the mentioned weight argument:
"Normalize by k-1, where k is the window length. If k=1, the weight is k."
(from Matlab documentation)
The 2 specifies the dimension along which to do the calculation.

When the same code is run with octave, it tries to interpret the 0 as
dimension parameter, because octave does not seem to support the weight
