ToDo

Core

• fix imread bug with opaque images, see https://savannah.gnu.org/bugs/?func=detailitem&item_id=36820
• remove removed but still referenced function in "seealso" blocks
• FFTW multithreaded https://savannah.gnu.org/patch/?7922

Forge

image

• implement SURF, integralImage is cumsum(cumsum(a,1),2)

brainstorming

• something like autobuilder for octave would be cool. Jordi mentioned http://hydra.nixos.org/jobset/gnu/octave-default
• perhaps http://www.phoronix-test-suite.com/?

Snippets

chain matrix multiplication

a=[1 2; 3 4];
b=[4 2; 8 1];
c=[2 3; 1 -1];
m=cat(3,a,b,c);
s=cell(3,1);
s{1}=a;s{2}=b; s{3}=c;
a*b*c
s{1}*s{2}*s{3}
mtimes(num2cell(m,[1,2]){:})
mtimes(s{:})
