メッセージ

I am a biomedical engineer. I have a PhD in Biomedical Informatics and a Masters in Library Science . My curriculum includes many graduate computer science courses. A medical engineering and information journal is to publish my research which applies neural networks to analyze medical images. I have developed new algorithms that detect anomalies in medical images and identify anatomical parts in an image. My algorithms temper unstable, finite dimensional linear systems, and are applicable to areas other than medical image analysis.I would like to share my algorithms with the MatLab community for solving ill-conditioned system, which are more stable and simpler than the MatLab SVD pinv() approach. Professional Interests: biomedical engineering, image analysis

Homework question I don't understand
Look at the plot for various x and R. Remember that R=4.6692016091 is a critical point. For example, if say x=.02 and R=4<4.6...

tikhonov(U,s,V,b,lambda,x_0) Error
OK, I know what I was doing wrong. Instead of the full SVD I should have used the compact SVD, namely csvd. In a compact svd th...
