Code: if (round(xw(1))>2) & (round(xw(2))>2) & (round(xw(1))<h-1) & (round(xw(2))<w-1) W0 = img(round(xw(1))-2:round(xw(1))+2,round(xw(2))-2:round(xw(2))+2); else NA=1; ...

I am working with Octave in the control package, and I want to take an array of transfer functions (initialized as follows) and just extract the diagonal elements of the matrix. Whenever I try to d...

I would like to draw a 3D histogram (with gnuplot or octave) in order to represent my data. lets say that I have a data file in the following form: 2 3 4 8 4 10 5 6 7 I'd like to draw nine col...

I have a set of frequency data with peaks to which I need to fit a Gaussian curve and then get the full width half maximum from. The FWHM part I can do, I already have a code for that but I'm havin...

In Matlab you can draw a circle by just specifying the center and the radius like this: R = 10; Center = [5,8]; circle(Center,R,1000,'b-'); hold on plot(Center(1),Center(2),'g.') The same code f...
