Examples#
In TeXForm#
TeXForm parses this entry as prefix syntax; the package determines its argument specification.
Expands to#
\functionalderivative{#1}{#2} \frac{\delta #1}{\delta #2}Internal reparse. Star uses \flatfrac. Single argument expands to \frac{\delta}{\delta #1}.
Collapse long functional derivative names to the fdv command.
\fderivative{#1}{#2} \fdv{#1}{#2}Equivalent forms#
\fderivativeexactPhysicsMappings registers all three names to the same Derivative handler with argMax=2 and op='
\\delta'.\fdvexactPhysicsMappings registers all three names to the same Derivative handler with argMax=2 and op='
\\delta'.
