let f(X) : Rn --> R be a function defined on convex set S s.t S is a subset of
Rn (real space n-dim). Let f is positive throughout. Then define g(x) = (f(x))^2. Prove that if f(x) is convex then g(x) is also convex.
hi want to read the rows of a matrix from a file which are written in the following way :
(2:1,3), (4:3,1), (2:1,8)
i am working in java, i am not able to figure out how to do this using bufferedreader :(
can someone help?
Thanks
yes, i will be considering tan from 0 to infinity, i.e all possible branches
and i need my solutions to be accurate. hence graphical approach won't work :(
Hi,
I have a class, say myclass and it takes two strings (let s and g ) and one int ( say i) as its arguments.
It looks like, public class {
String s , g;
int i ;
public void myclass(String sname, String gname, int k){
s = sname;
g = gname;
i = k;
}
}
Now, I have several...
Hi all,
I have a filter whose amplitude and phase response in terms of w(omega) is known to me which i calculated numerically. Hence, the value is known only for discrete values of w(omega).
Now, I want to know the output which this filter will produce on sending a temporal pulse(pulse in...
We know that hilbert transform is a linear filter whose frequency response is given as -j*sgn(f), where f is the baseband frequency. Hence magnitude response of this filter is 1 and phase response is -pi/2 for f > 0 and pi/2 for f < 0. Hence phase response curve is like a staircase function (...
hi, i want to stick 4 fibers of outer diameter 200 microns each ( with their jackets peeled off) together in perfect square geometry. How it can be done?
which equation can be used to know the image size formed by a thick lens
e.g. I want to know the height of the image formed of an object 0.03 cm high. Which equation can be used
