Please consider adding support for octave-mode to recognise the (MATLAB) keyword 'spmd'. This should include that the 'spmd' keyword can match a corresponding 'end'.
When using octave-mode to edit MATLAB code that uses the keyword 'spmd', the indentation becomes incorrect.
This keyword can be used with the following syntax (see https://se.mathworks.com/help/parallel-computing/spmd.html
Since octave-mode doesn't understand that the 'end' is supposed to match the 'spmd', later code blocks get incorrect indentation as
octave-mode thinks there's an extra 'end' in the code.
