  Renames x86_64 specific asm files

  Renames all x86_64 specific assembly files to consistently
  end in _x86_64.asm. This will be useful for build systems to
  handle these files differently.
  All new 64-bit specific assembly files should use the new
  naming convention.

• avutil/tx_template : Don't waste space for inexistent factors

  22 octobre 2022, par Andreas Rheinhardt

  avutil/tx_template : Don't waste space for inexistent factors
  It is possible to avoid the factors array for the power-of-two
  
  tables for which said array is unused by using a different
  
  structure for initialization for power-of-two tables than for
  
  non-power-of-two-tables. This saves 3*15*16B from .data.

• Animation with gnuplot : only one cruve plotted in an animation whereas 2 expected

  26 mai 2022, par stefan

  I have the following script which is expected to produce the animations of 2 curves :

  


  #!/bin/bash

for i in {1..397}; do
gnuplot -p <<-EOFMarker
set terminal png;
set output "pic$i.png";
set title "power spectrum";
set xlabel "scale (k)";
set ylabel "P(k)";
set key top left;
set grid;
set ytics out nomirror;
set xtics out nomirror;
set logscale x;
set logscale y;
set format x "10^{%L}";
set yrange [0:30000];
plot "CAMB-1.3.5/matter_camb$i" u 1:2 w l;
replot "EFTCAMB_v3_beta/matter_eftcamb$i" u 1:2 w l;
EOFMarker
done

# Build movie with ffmpeg
ffmpeg -start_number 1 -i pic%d.png  movie.mpeg


  


  Every works fine excepted the fact that only one curve is plotted in animation (CAMB-1.3.5) :

  


  Here is an example of frame :

  


  

  


  Why the "replot" command is not taken into account in the generated image ?
