hi there, i need to do image segmentation using region growing technique..can anybody help me with it...? i found a code in mathworks. this is the link for it http://www.mathworks.com/matlabcentral/fileexchange/19084-region-growing but i couldn't really run the program...the program runs, accepts the seeds, but do... 1 Apr 2010 12:21

Error!
Hello I'm trying to ceate a 3x3 array of random numbers from 1 to 9. I'm using the following code with which I get the error : Attempted to access r(0,1); index must be a positive integer or logical. Error in ==> Untitled at 6 while (t == 1 && (k==2 && r(t,k) == r(t,(k-1))) || (k==3 && (r(t,k) == ... 1 Apr 2010 12:21

Relations: Stuck need help
|.| that is the modulus sign. i am trying to solve that question using M-file... that is the question that was given to me and i am trying to solve it.... i think in this case i need to find a way how to generate the first 100 terms of f(n+1) when f(0) = 1 and f(1) = -2 im not sure if this made it any clearer ... 1 Apr 2010 11:14

Relations: Stuck need help
Dear Rock! Generate the first hundred terms of the following recurrence relations: a) f(n+1) = (-1)^n * f(n)/[|f(n-1)|+1] where f(0) = 1 and f(1) = -2. This is my attempt at answering: question a): function f(n), f(n+1), f(n-1) f(n+1) = ((-1)^n) * f(n)/f(n-1)+1; where f(0) = 1 and f(1)... 1 Apr 2010 11:14

Conversion question
Hey Community, I had posted a question not too long ago that I think might have been vague, so here I am trying again from more research. I found a function: [x,y,z] = lv2ecef(xl,yl,zl,phi0,lambda0,h0,ellipsoid) That converts local vertical to geocentric (ECEF) coordinates. This function converts based on pos... 1 Apr 2010 11:14

TimerFcn Callback
I am trying to implement a TimerFcn for an analoginput object that plots some data every few hundred milliseconds, but I have been running into some odd behavior. I have simplified my code so it can be debugged by anyone that can create an analog input object using a winsound adaptor. The main issue is that if I ca... 2 Apr 2010 08:10

Problem: Modelling DC-Motor using Simscape Language
I am stuck on creating a simple DC-Motor in Simscape language. My code so far looks like this: component DC_mot % DC Motor inputs U = { 0, 'V' }; % n:left end nodes r = foundation.mechanical.rotational.rotational;; % r:right end parameters ke = { 0.544, 'V*s/rad' }; km = { ... 1 Apr 2010 10:07

decoding repetition code
hey all, i made a repetition coding using repmat function. for example: x = [1 0 1 1]; y = repmat(x,3,1); z = reshape(y, 1, 3*(length(x)); i want to decode the repetition coding without using a for loop because it will take too long if x is big.. thank you for your reply Elie ... 2 Apr 2010 04:56
