[julia-users] matrix multiplications

[zamani . majid1989]

hi guys
is there a way to reduce allocated memory in matrix multiplications?

for example this code blew in my machine gives :

function test4(n)
  a = rand(n,n)
  for i = 1:100
     a*a
   end
 end


---------------------- answer  ----------------------
test4(1)
# force compiling 

@time test4(1000)
16.589743 seconds (433 allocations: 770.587 MB, 0.68% gc time)
