Curve fitting with 5 data points?
Hi, I have five data points and I need to show that they can be fitted by parabolic fitting. 1. Is it ridiculous to run a fit with 5 points only? 2. Is there any possible bootstrap approach (similar to linear regression with small amount of data), which can demonstrate reliability of my fit? 3. Is the curve fit ... 2 Aug 2010 12:32

Stateflow dashed transitions
Hi, I've copied a part of stateflow diagram from one model to another and now part of the transitions lines are dashed (they look like ones which are disconnected) and have numbers attached to them but most of the time they are single transitions from the state so it's not the execution order. When I click on the... 2 Aug 2010 11:25

removing noise from signal
Hi all, i have a problem with removing noise from signal. so, this is my code: f = 7000 %frekvencija l = 100 %duljina signala T = 1/f t = (0:l)*T x = 0.1*sin(2*pi*45*t) + sin(4*pi*220*t) y = 0.7*sin(2*pi*750*t) + sin(2*pi*120*t) z = x + y subplot(2,1,1) plot(t,z) xlabel('t[s]') ylabel('A') Z = fft(z) ... 4 Aug 2010 16:53

Cross-correlations - how to read
Hi all, I crosscorr use the crosscorr(x, y) function and it creates me a very nice chart for the first 20 values. It creates the two sides, the values on the axis OX> 0 and value <0. How to interpret this chart? Is the value of> 0 on the X axis is the x values are delayed terms y, and for <0 is the other way ar... 5 Aug 2010 18:02

filter fft data
Hi I have a data-set (variable star light-curve) that is sampled non-uniformly (avg sampling 0.548Hz) - I re-sample the data by using 'interp1' over a new time-vector specified within the same begin/end values of original (sampling 1Hz). Total time is 4.8hours. I am looking for the rotation period of the star - w... 2 Aug 2010 10:19
