Support vector machine Regression (SVMr)

Hi, All I would like to thank you in advance for your help and assistance. I want to implement Support Vector Machine Regression in MATLAB, unfortunately there is no inbuilt function for SVMr. I would be great grateful if any one assist me. I got dataset 500x1235, just only one class. any file sharing or MATLAB code available to analyse that dataset. Thank you

I also need this , there is a function but it is in the bioformatics toolbox...dissapointed as I thought it would be included in either the Stats toolbox or the NN toolbox. But you can get this free on the Web , look up SVM Toolbox in Google ...unfortunately its not supported by Matlab ..which is not pleasant to say the least!
