graph of cumulative functions
Good evening I'm searching to compute the graph of this function: F(y)=lF(y/r) if 0<=y<=r F(y)=rF((y-r)/l)+l if r<y<=1 with r+l=1 and r different from l. However I cannot do this, my matlab doesn't want to give me a graph! ;) I don't know how to do because I have to use the function in the definition of this func... 25 Mar 2010 17:25

libSVM question
in libSVM, do you have to give a test label for each of the instances you want to test with? What if you have no idea on the class - this will reduce the accuracey. Can libSVM not predict the class, or at least tell you which instances you got right? Out of the instances you guessed the class right, is there any cha... 26 Mar 2010 13:09

Concatenate from a for loop
Hi, I have a for loop that calculates the position of a planet rotating about the sun. It uses ode45 and in iteration of the loop, calculates 11 values of x, y, xdot and ydot. This is done by initializing initial conditions and then resetting the initial conditions as the final conditions(11th) of each iteration of th... 25 Mar 2010 14:58
