view scripts/plot/private/__gnuplot_has_feature__.m @ 16108:3cce6b4e0f7c
Update gnuplot plotting scripts for faster or more modern synta
* scripts/plot/__gnuplot_drawnow__.m: Use default values in function header.
Check number of arguments to function immediately. Use single quotes to
avoid lots of backslashing. Use strtok() to replace hand-coded functionality.
Initialize persistent variables in declaration (10% faster).
* scripts/plot/gnuplot_binary.in: Replace tabs with spaces. Simplify input
validation. Add %!test block.
* scripts/plot/private/__gnuplot_get_var__.m: Use default values in function
header. Use "*char" in fread to automatically convert to char variable.
* scripts/plot/private/__gnuplot_ginput__.m: Check immediately for required
version of gnuplot. Use "*char" in fread to automatically convert to char
variable. Use fputs in place of fprintf to match rest of code.
* scripts/plot/private/__gnuplot_has_feature__.m: Initialize persistent varibles
in declaration. Use false () rather than logical (zeros()) construction.
* scripts/plot/private/__gnuplot_has_terminal__.m: Use strtok() to replace
hand-coded functionality
* scripts/plot/private/__gnuplot_print__.m: Replace sprintf calls with direct
string char matrix concatenation (2.4x faster) where possible. Replace for
loop with multiple argument form of set(). Use single quotes to avoid lots
of backslashing.
* scripts/plot/private/__gnuplot_version__.m: Use single quotes to avoid lots
of backslashing.
