Hello Wolfgang,

thank you for the patch (not in today's beta); I also attach the modified strc-mat.mkiv and a test file.

Two questions:

1.

What exactly are

   %\startsubformulas[+]       % These two options for \subformulas
   %\startsubformulas[mylabel] % enable subnumbers for the formulas

intended for?

The simple "\startsubformulas[eq:b]" meets my needs (subformulas are sub-numbered) and I can't see any difference to "\startsubformulas[+]".

2.

Is there a way to setup numbering subformulas to "(1a)" form instead of "(1.a)", i.e. set the separator to ""?

Best regards,

Lukas
