curve fitting
Hello In the attached mfile,I am : 1. calculating the series resistor (Se_R) and shunt resistor (Sh_R) of an attenuator for various values of attenuation. This works fine. 2. calculating the current (Id) vs resistance (R_total) of a PIN diode. This also works fine. 3. How to calculate (id) for the values ... 4 Sep 2009 14:19

coefficients of b-spline
Dear community, For the given x and y=f(x) values, I would like to obtain b-spline coefficients. How do I obtain these coefficients? I there an easy and fast way to do this with Matlab? Example: N=number of nodes xi=0; xe=pi/2; x=linspace(xi,xe,N); y=sin(x); if quadratic b-splines are constructed, then th... 11 Sep 2009 18:30

Not sure if I am asking this correctly. In a previous development environment that we are porting over from, there was a concept of bubble calls that would cause the bubble to immediately execute the function that was connected on the other end like an interrupt. Is there a way in an S_Function to have a pin behave i... 4 Sep 2009 09:49

Interpolation from monthly to daily

"Alexander Torgovitsky" <atorgo.remove.vitsky(a)gm.remove.ail.com> wrote in message <h7gjv8$l0m$1(a)fred.mathworks.com>... I have several subplots that share the same colormap. I'd like to add a colorbar. My subplot looks like 4 plots stacked on top of each other (i.e. 4 x 1). I would like to make my colorbar span the e... 4 Sep 2009 09:49

gauspuls and ode
Hello. I'm pretty new to Matlab, and would most appreciate it if anybody could give me some pointers. I am working on some rate equations which I've solved using the ode45 function. However, I now will want to put in a gaussian pulse into the equation -- BUT am getting really muddled as to how to incorporate gauspul... 4 Sep 2009 01:05

Harris Laplace Method
For last couple of days, I have been trying to code for Harris-Laplace method. I got some code for harris corner from this site. But I am getting trouble due to some confusion. Can any1 give me the code of that? or at least some guideline without the reference of paper? First confusion comes from integration scal... 4 Sep 2009 01:05
