I have some functions involving large matrix multiplication in my code. A sample code is as follows.
function foo1() temp = Array for i = 1:1000 push!(temp, randn(400,400)*randn(400,1000)) end end function foo2() for i = 1:1000 randn(400,400)*randn(400,1000) end end @time foo1() @time foo2()
I find that
foo1() takes 17 seconds. Without
foo2() takes 11 seconds. Is there any way to improve the speed of
foo1()? Thank you.
