Deriving empirical equation using neural network
Hi, I am new to the forum and would like to get some suggestions and help to the following: I have to linearly relate 3 inputs to one output and derive an empirical equation in neural network. The equation is of form as given below: y = a*x + b*w + c*z + d; where: y is the output, a,b, and c are coefficients... 5 Mar 2010 02:53

Finding turning points in a curve
Hello--- I am wondering if there is a way in Matlab to find the turning points of a curve using discretely-sampled data. I've applied the Savitzky-Golay smoothing filter to determine the first and second derivatives. Is there a way to search for "zeros," or alternately where "zeros" can be approximated? ... 18 Feb 2010 09:26

Trying to use invfreqs
hello, I am trying to use invfreqs to get the transferfunction from frequency response data. I have the frequency response measured at 0.5 Hz, 1Hz, 2HZ, 4Hz and 6Hz. I used a 3rd order for the numerator and 4th order for the denominator. The complex frequency reponse is as follows: 30.56 + i 3.143 33.75 + ... 23 Feb 2010 11:17

toeplitz matrix
Hi all, I am trying to create a toeplitz matrix which will be of a really large size. In fact, when doing a symmetric for r = 9216x1 toeplitz(r) I get an error. The worst part is that this is a small r for what I need, so I wanted to ask what there is in terms of a solving Ax = b for x, given b and that A is a... 18 Feb 2010 22:56

problem to get continuous output in neural network
hi.. i'm working with mlp neural network using matlab. i have to predict an equation. i use continuous input and need to produce continuous output. But, i have problems here. how can i have continuous output because the neural network that i have learned before just produce discrete value output such as 0 or 1 only..... 19 Feb 2010 12:05
