Extended Kalman Filter Problem
"Robin Roche" <robin.roche(a)removethis.gmail.com> wrote in message <gptint$lmv$1(a)fred.mathworks.com>... Hi, I am currently developping an algorithm to determine the state of charge of batteries thanks to an extended Kalman filter. My problem is that although the voltage prediction is good, the state of char... 22 Mar 2010 00:21

specifying the bitdepth and color map of a bmp file in imwrite
I am running into two issues trying to read and write bmp images. My images are grayscale 24bit BMPs exported from photoshop. first I read the file [I,map] = imread(filename,'bmp'); it runs without error but map is an empty matrix. This creates an error with imwrite if I use imwrite(I, map, ne... 17 Mar 2010 04:40

Importing Data from Excel to MATLAB in Real Time
Hi, I want to import data from an Excel file onto MATLAB in realtime. I am currently importing using a xlsread(), processing the data and then plotting it using the tools on MATLAB. Consequently, the data I see is only valid for the time at which it was imported. Is there a way to make it constantly refresh and update... 22 Mar 2010 10:30

Interfacing MATLAB with BASIC Stamp 2
Hi, My name's Allan and I'm a senior engineering student at the George Washington University. For my design project, I would like to create a GUI in MATLAB that would allow me to interface with a BASIC Stamp microcontroller to control a set of stepper motors. I have already created a GUI in MATLAB for another part o... 16 Mar 2010 23:12

How to count time stamps in a mat file
I am super new to MATLAB. I have huge chunks of data and I would like to to find out the amount of time a particular data value is above or below 0 . I want to count the total time when my value on the y axis is above or below zero as percentage of total time. Even a histogram showing the amount of time the data value... 16 Mar 2010 22:05

Simulink fixed step solver
Hi, I'm having trouble getting a fixed step solver in Simulink to give reasonable results. I have a controller and model in Simulink which simulates fine when using ode23s (fast and slow dynamics present). Even when I change the max and min step size to almost the same (0.0049 and 0.005) the simulation runs fin... 16 Mar 2010 22:05
