RE: Octave propablity rand and randn

[William Krekeler]

I think he wants the PDF of some input vector.

 

Look at:

http://www.gnu.org/software/octave/doc/interpreter/Distributions.html

 

or to compute from a given x doing something like this

 

Nelements = 1000;

X = randn( Nelements );

xstd = std(X);

[ N, Xhist ] = hist( X,  (-10*xstd):(xstd/10):(10*xstd) );

PDF = N./ Nelements;

figure,plot( Xhist, PDF )

 

Also note, 'help command_name' will give you the help for that command.
