There are a number of tools that can do that for you.  Note that the
choice of tool often depends on both the container file format
(Matroska, in your case), and the codec used on the video and audio
streams within.

I've used "mkvmerge", a command-line application, with success on
HandBrake-created Matroska files encoded in H264.  Despite the name,
mkvmerge also splits files.  Look for the "--split" option in the man
page.  There are examples included that are easy to adapt to your
needs:

    5. Keeping specific parts by specifying frame/field number ranges while discarding others.
  
       Syntax: --splitparts-frames:start1-end1[,[+]start2-end2[,[+]start3-end3...]]
       
       Examples:
       
        1. --split parts-frames:137-258,548-1211
       
        2. --split parts-frames:733-912,+1592-2730
       
        3. --split parts-frames:-430,2512-
