We are given a noisy measurement ymeas 1 ,. The sequence y is the signal we are interested in, and the sequence v is the residual or noise in the AR model, which we assume is small, or at least, not large. Express the gradients using matrix notation. Please solve these problems exactly, i. More generally, the linear equations might come from various conservation laws, or balance equations mass, heat, energy, charge. The algorithm you will discover is called back substitution, because you are substituting known or computed values of xi into the equations to compute the next xi in reverse order.

External information enters each of the m regular nodes and flows across links to the special destination node. The locations are users of a social network, the edges represent friendships between users, the quantities are user parameters of interest say, to advertisers , and the measurements are noisy estimates of the parameters obtained from other sources or information. One situation where this problem comes up is a nonstandard filtering or equalization problem. When the output of gate i is connected to an input of gate j, we say that gate i drives gate j, or that gate j is in the fan-out of gate i. Still, you can solve it with material we have covered. Note that if we fix the VAR coefficients A1 ,.

PN a Find the best affine fit, i. If A and B are onto, then so is the matrix.

We will take the first n cells, at positions x1y1. You must justify that any matrix inverses you use actually exist; you cannot simply assume that matrices appearing in your solution are invertible as we often let you do.

We will take the first n cells, at positions x1 ee263, y1. So just ignore this while doing this problem. In this problem you will use matlab to solve an optimal control problem for a force acting on a prooblems mass. In cases where there is a right inverse B with the required property, you must briefly explain how you found your B.

A message or packet can be sent from one node to another by a sequence of transmissions from node to node.

Produce and submit scatter plots of y i for xln and xmmse. If we are really unlucky, the system will fail in such a way that y is still consistent.

Copy this file to your working directory and type uy data from within matlab. Your job is to choose these parameters to minimize E. Plot the optimal force fand the resulting p and p. A data network is modeled as a set of l directed links that connect n nodes.

Write down the values of xln and xmmse you found. This signal is received at n base stations, located at locations s1. We consider a standard estimation setup: Clearly explain your method.

We do not assume it homwwork controllable. For this reason, Householder reflections are used as building blocks for fast, numerically sound algorithms. Check your placement against various others, such as placing all free cells at the origin.

It then adjusts its source rate proportional to the sum of the congestion along its route. Specifically you will choose coefficients a0b1.

In real congestion control, the rates and traffic are nonnegative, homeworkk the traffic on each link must be below a maximum allowed level called the link capacity. The data are organized as vectors of length Most of the linear algebra you have seen is unchanged when the scalars, homewokr, and vectors are complex, i. Explain how to solve this problem. This means there are no reaction rates consistent with cell growth, flux balance, and the gene knockout.

You can check that at each period, the transmission used is active, i. When the vehicles are docked, i.

Find the purchase quantities b1. In this problem we consider a function f: Fish that are less than one year old in the current year t bear no offspring.

Give us a and b, and submit the code you used to find a and b. We define the spherical distance between two vectors on the unit sphere as the distance between them, measured along the sphere, i.

Thus, for example, w13 gives the wire width of inductor
