• part of the slavish pluralization phenomenon. I presume the math world got 'matrices' from 'vertices', though the two have crucially different singular endings.

• I'm not sure why you consider this an example of slavish pluralization.

'matrix' is a third declension Latin noun, with the following case forms:

*** Singular Plural

nom. m�?trix m�?trīcēs

gen. m�?trīcis m�?trīcum

dat. m�?trīcī m�?trīcibus

acc. m�?trīcem m�?trīcēs

abl. m�?trīce m�?trīcibus

voc. m�?trix m�?trīcēs

Thus, 'matrices' is the correct plural form.

Similarly, 'vertices' is the correct plural form of 'vertex', because vertex is also a third declension noun. The difference in vowels in the singular ending is immaterial, and not - as you suggest - 'crucial'.

• Latin matrix has a stem ending in /i:k/ and regularly forms its nominative by adding /s/. So also the mathematical term 'directrix' ~ 'directrices', as well as rare female agent nouns such as 'executrix'.

Vertex (doublet of vortex in Latin) owes its stem vowel to the fact that in Old Latin unstressed short vowels before a single consonant became /i/, thus plural /wertike:s/; but before two consonants, /e/, thus /werteks/. So also 'apex' ~ 'apices'. This alternation didn't apply to the long /i:/ of /ma:tri:k-s/ ~ /ma:tri:k-e:s/.

• What's the correct way to pluralize "dominatrix"? My college friends and I used "dominatrices", but that may have just been wishful thinking.

• That's right: the -trix in all these is the female agent ending (feminine of -tor), so they all go the same.

I should add that the traditional English pronunciation would be /-'traɪsiːz/ with shift of stress to the long vowel, but the most common one, matrices, is now firmly established with stress the same as the singular, so that might be preferable for all the others too.
