The data provide for Homework 4 was not provided with any units of length for the coordinates.
Since the coordinates were between 0 and 1, the coordinate system was assumed to be set in a two
dimensional plane. T
The Phase retrieval problem
The aim of this paper is to build up the theoretical framework for the recovery of
sparse signals from the magnitude of the measurement. We first investigate the
minimal number of measurements for the success of the recovery of
Question 1: A die is rolled, find the probability that an even number is obtained.
Solution to Question 1:
Let us first write the sample space S of the experiment.
S = cfw_1,2,3,4,5,6
Let E be the "an even number is obtained" and write it down.
E = cfw_2,
