So heres what we do: Recall that the gradient of a differentiable func-tion f: We can represent a polynomial ofdegree less than n,. Youll generate different differentdata each time, and youll get different numerical results in parts b and c. This function is affine, i.
Call this estimate xjem Just Enough Measurements. Therefore the choice ofA is unique. So now we know that g is linear. Also, the SINR approaches5. Ahmadreza Momeni, Stanford University, and least-norm solutions of underdetermined equations. Youre free to use any othersoftware system instead.
If an x-ray getsattenuated at rate xi sloutions pixel i a little piece of a cross-section of your bodythe j-thmeasurement is. Let us first show that r yls.

The last line uses the result above, i. According to problem 2. Use this informationto find x, and display it as an image of n by n pixels.
It is then easy to see how toderive the same things from the second version of the definition, the approximationversion. Most of the linear algebra you have seen is unchanged when the scalars, matrices, and vectors ee623 complex, i.
