This code will generate the coherent state of any dimension of field.Here the inputs are complex amplitude and dimension.
Ex: Coh=coherentstate(3,40)
here 3 is the amplitude and 40 is the dimension of field. It will generate a column matrix of dimension 40.If u will plot this state, it will be a poissonian distribution with peak at 'alpha'*alpha'.
in my example, peak will occur at 9.

Object oriented program demo: animated traffic lights on road intersection

Only 31 lines of code in start.m is used to control animated traffic lights on road intersection. LampSuperclass and three clases (trafficLamp, tLamps, map) are used in program. Classes define (1) single Red-Yellow-Green traffic lamp, (2) set of four lamps (North, South, East, West direction) and (3) map of street intersection. Menu is used to change the mode of traffic light operation.

positive degree day for normally distributed temperatures

PDD fraction in a normally distributed climate
  Calculates the probability weighted positive degree days for normally distributed temperatures:
    T_june = 3; %degC
    sigma_june = 7; %degC =std(daily_average_temps_june)
    PDD_june=30*normalpdd(T_june,sigma_june) % units: degC*days
    PDD_factor = 8e-3 %m/day/degC <- different factors exist in litterature.
    melt_june = PDD_factor*PDD_june % meters of melt.

Thanks Alan,
I don't know whether my problem is locally singular or not. Can you suggest me how to check local singularity.
Is there any options in fsolve for this type of functions?
Compare current image with previous image
Hi all,

I need some help with the coding. How to compare current image with the previous image? I want it compare image 2 with image 1, image 3 with image 2,image 4 with image 3 and so on.


for image=1:10;
     img = imresize(im2, [360 480]);
     img = rgb2gray(img);

     im1 = img-1; ******* problem part
     uv = estimate_flow_ba(img, im1);

This is what I do but it seems uncorrect. Anyone can help me?
Thanks a lot.
