    image processing problem

    I use fast hough transform for barcode localization .However , if i apply this transform, i obtain above figure .I wanna obtain the exact barcode area using this figure for decoding

    Passing arguments between functions in Matlab

    Re: Matlab help For exp. let say your function name "help" then [xout,yout]=help(ar1,ar2,ar3) ar1,ar2 and ar3 your input argumants and also xout and yout are your return values.you can call this function like this >>[xout,yout]=help(1,2,3) then command returns outputs values

    How to generate 100 sample data using the AR(1) model?

    how to generate 100 sample data using the AR(1) model?I have generated but I don't know this code is true or not.And also how can i calculate the autocorrelation matrix? "a=0.5; n=0.001; x(1)=100; for k=2:100 x(k)=a*x(k-1)+n; end"

    linear algebra question

    Hi everybody How I can generate basis vectors for a 8x8 matrix which is known?I think that first colon of the matrix is basis and others colons are also basis for a 8x8 matrix.This is true or not . Thanks

    implementation of backprop using tansig doesn't work proper

    tansig network -------------------------------------------------------------------------------- Thank u your reply but my data set values are btwn -1 and 1 so i must use tansig.If i use matlab toolbox (chosen tansig),there isn't any problem .Thus tansig must work my matlab code.

    implementation of backprop using tansig doesn't work proper

    tansig Hi I'm implementing an NN using Matlab to learn the XOR problem: - in in out -1 -1 -1 1 -1 1 -1 1 1 1 1 -1 Its a multi-layer feedforward network, and the neurons are either unipolar 'logsig' or bipolar 'tansig' neurons. It learns succesfully using logsig neurons, but with tansig the...
