We +merely summarize them here, since they come with their own <code>man</code> +pages for Unix and GNU systems (with HTML versions on our web site). + + <p>The first program is <code>fftw-wisdom</code> (or <code>fftwf-wisdom</code> in +single precision, etcetera), which can be used to create a wisdom file +containing plans for any of the transform sizes and types supported by +FFTW. It is preferable to create wisdom directly from your executable +(see <a href="Caveats-in-Using-Wisdom.html#Caveats-in-Using-Wisdom">Caveats in Using Wisdom</a>), but this program is useful for +creating global wisdom files for <code>fftw_import_system_wisdom</code>. +<a name="index-fftw_002dwisdom-utility-289"></a> + + <p>The second program is <code>fftw-wisdom-to-conf</code>, which takes a wisdom +file as input and produces a <dfn>configuration routine</dfn> as output. The +latter is a C subroutine that you can compile and link into your +program, replacing a routine of the same name in the FFTW library, that +determines which parts of FFTW are callable by your program. +<code>fftw-wisdom-to-conf</code> produces a configuration routine that links +to only those parts of FFTW needed by the saved plans in the wisdom, +greatly reducing the size of statically linked executables (which should +only attempt to create plans corresponding to those in the wisdom, +however). +<a name="index-fftw_002dwisdom_002dto_002dconf-utility-290"></a><a name="index-configuration-routines-291"></a> +<!-- --> + + </body></html> +
