After I profiled my programe, I found that the most time consuming part (
self time) in a function f(...) is something like this:
[A,B,C]= g(x,A,B,C);
I'm wondering why this statement will be slow? Since it's self time of f(...
),
it's not the time within function g(...). Does this mean the time is
consumed in copying matrix parameters A,B,C ? How can I i
