Simulink - creating neural networks (gensim & NN toolbox)
Hello, I am trying to construct a neural network for use within the simulink enviroment from labeled data that I have generated and saved within the matlab workspace. Although the network simulates (sim(net,'input vector') and throught the use of the NN toolbox) without any problems I receive the following error m... 1 May 2010 02:14

conting number of tuberoclosis baclili
hello sir, i am working on a project to count the no. of tuberolcosis bacili in the image. firstly i am thresholding the image & then i am using the binary image for counting . sir i've seen you cell counting post. i've tried the same codes in my image as well but it's not working properly in the binary image that ... 1 May 2010 05:28

what does this line of code do - comparison?
i have r = -1; then i do: r = max(abs(-(1/(h)^2) * ( fi(i-1) - 2 * fi(i))),r) what does the above do? is it comparing the new value of r to the old value of r (which is -1)? tis matlab. tnx. ... 1 May 2010 02:14

Extract modal parameters from MATLAB
Hi All, I want to extract modal parameters(frequency, mode shape, damping ratio) of my finite element model. Is there any method to do that? When I searched internet, I found vibratools, modaltools but we have to buy them. Can anyone give me an idea? ... 1 May 2010 01:09

System identification of Kalman Filter noise matrices
Hi all, I'm trying to fit my Kalman Filter into an existing feature tracker. I need to tune the process noise and measurement noise covariance matrices and I was told it could be done through system identification. Can anyone please guide me through the process using Matlab? PS: assuming white noise ... 1 May 2010 07:37

Systems of partial differential equations in 2 spatial variables?
Does MATLAB have the capability to find numerical approximations for systems of partial differential equations in two spatial variables as well as time? Specifically I'm interested in a pair of reaction-diffusion equations each involving a simple laplace operator: dF/dt = (d^2F)/(dx^2)+(d^2F)/(dy^2) + Z(F,G) dG/d... 30 Apr 2010 21:52

real-time object tracking using optical flow / XY coordinates needed
hello every one,,i'm doin my grad project,,and i want to track in real-time a swarm of mobile robots using a webcam and know their locations,,i've used Optical Flow,,Horn Schunck to track the objects,,,,it works well and track moving objects only in the environment,,now i want to know their coordinates on the simulink ... 30 Apr 2010 20:45

symbolic equation conversion for use in ode solver
I want to write a program that uses the symbolic math toolbox to manipulate a function (differentiate, add/multiply) to create several new expressions which I want to solve numerically (ode45?). for example: f = xdot = ax / b+x Manipulation: gdot = g* df/dx + df/da hdot = h* df/dx + df/db System Matrix: z ... 1 May 2010 04:24

s function code from m file
Hi all , i have a function called the dynamic programming. i have the m file function and i want to build this function in Simulink . i tried days and weeks to bulid this as blocks but i failed . I asked for this , they told me that converting it to s-function block is easier but i have no idea of s-function ... 30 Apr 2010 19:39
