The methods I am aware of for modifying vertical spacing in a table are renewcommandarraystretch<length> and setlengthextrarowheight<length>. However, these commands affect the arrays inside the table as well.

Is there any command similar to setlengthtabcolsep10pt but for row spacing?

This is the code for my table, and I'd like to increase the spacing between the matrices, as they look too close to each other.

A tabstackengine approach. Column gap set with setstacktabbedgap, and extra matrix vertical gap set by optional argument of addstackgap (found in zz definition).

If you wish to adjust the row spacing of the inner arrays, use setstackgapL<length> to define the baselineskip.

Here is an alternative using the cellspace package:

usepackagecellspace
setlengthcellspacetoplimit6pt
setlengthcellspacebottomlimit6pt
