Youll generate different differentdata each time, and youll get different numerical results in parts b and c. This gives the matrix. MA Assignment 3. If an x-ray getsattenuated at rate xi in pixel i a little piece of a cross-section of your body , the j-thmeasurement is. For complaints, use another form. There is such a matrix ifand only if A is full rank, which it is. In this problem we consider again the power control method described in Suggest us how to improve StudyLib For complaints, use another form.

PHY February 17, Exam 1. Least-squares approximations and least-norm solutions; you will be responsible for homework and exams. EE Autumn Prof. Now it is easy to seefrom 1 that UT x x. Clearly, from the lecture notes, this represents a rotation. Now suppose we have N line integral measurements, x1 x2 x3 x4 x5 x6 x8 x9 l2 l3 l4 l5 l7 so,utions L Figure 2: Use this informationto find x, and display it as hokework image of n by n pixels.

Show that U is either a rotation or areflection. Rn R, at a point x Rn, is defined as the vector.

The following script carries out all parts of the problem. In this problem we explore a simple version. In fact, there are many right inverses of A, which opens the possibility that we canseek right inverses that in addition have other properties. The problem is to estimate the vector of densities x,from a set of sensor measurements that we now describe.

Since UT x2 0 we have UT x2 x2 and we aredone. This is often called the best linear fit.
