pwelch
Hi, Is it correct that for pwelch, the data sequence n is divided into 8 section of equal length with 50% overlap. if I do not specify nfft, the default value is 256, i.e. if the length of segment is inferior at 256, it is completed by a zero padding to 256 length sequence to compute the fft in ecah sequence. ... 9 Apr 2007 05:09

plotting into multiple axes
I am trying to plot 2 lines over an image and the x coordinates of the image and the lines need to be correlated. for example: im=rand(50); im_x=linspace(0,10,50); im_y=linspace(0,100,50); x=linspace(1,10,100); y1=5*cos(x)+5; y2=5*sin(x)+5; creates a 50x50 image and 2 lines with 100 points each, but th... 5 Apr 2007 13:57

Simulink if loop
Hello experts, In my model in Simulink, I have a loop with an integrator, e.g. the model in this figure: <http://juriansluiman.nl/storage/16/example.JPG> Here includes the B subsystem an integrator. The input from B cannot be zero, so I tried an if-case with two if-action subsystems. After the sum, I detect ... 21 Mar 2007 07:51
