Mux Problem
I have a problem with a Mux operator in R2009 and R2010: I have three single values entering a Mux and one output array with three values. When I compare with "to Workspace" block the input values and the output array I have to take note that the first and the third value was devided by 1000 while the second value w... 11 Mar 2010 10:00

serial data plotting
Hi to everyone; I've a system sending digitalized ECG signals in 200 Hz to the PC by using RS232 port. I want to plot the datas coming from serial port. I need a realtime monitoring system and i need to see datas comin from serial port like watchin it on an ossciloscobe. So how can i do this acion bu using user interf... 11 Mar 2010 08:54

Fast Fourier Transform of data
Hi, I would like to perform a fast fourier transform of my measurement data. I used the script below, but I doubt if it is correct. The plot is not what I expected: I was expecting to see a big disturbance of the electric power at 50 Hz (due to a nearby machine), but I see the big disturbance at 100 Hz, 200 Hz and 3... 11 Mar 2010 10:00

noob: 3D plot with colour as 4th dimension?
I have recently stated using MatLab and have come across a problem with plotting: I have data [x,y,z,gain] and would like to represent this on a plot of some sort. What I am thinking is a 3D plot of (x,y,z) where the colour of that point is defined using a colormap (hot) for the value at that point. Is thi... 11 Mar 2010 07:48
