# vertical spacing in multiline gather with amsmath [duplicate]

I have gather* section with three lines. the lines appear all bunched up with hardly any space between them. How can I spread them out a little?

I tried \belowdisplayskip=12pt but no matter what value I chose there was no discernible difference to anything

\f{gather*}


Where \f{environment} is equivalent to begin{environment} for Doxygen that I am using.
• \baselineskip is the controlling length or use \\[1cm] instead of \\  also \mathrm{address} – David Carlisle Dec 7 '16 at 19:24
• also why \nobreak? (there is no possibility of a break at that point) – David Carlisle Dec 7 '16 at 19:25
• an explicit skip plus the asterisk to suppress a page break will work if input in this order: \\*[1cm]. if the asterisk follows the optional skip, it will simply be set at the beginning of the next line. (just tested. doesn't seem to be mentioned in the user's guide; will make a note to check that and add if it's really not there.) – barbara beeton Dec 7 '16 at 19:52
