ISYE 8803 HW7 Let be random matrix. Consider three different methods for generating : 1- iid Gaussian 2- random rows of a discrete cosine transform 3- consecutive rows of a random Toeplitz matrix For each case, set = 1024. The number of observations varies from 50 to 1000 with step 50. The sparsity varies from 25 to 500 with step 25. You can create sparse vectors () at random using any model you find reasonable. Calculate the probability of successful recovery for each choice of and by repeating simulation at least 5 times. A successful recovery is defined as 2 < 103 where is your recovered vector. Use your simulation results to determine values of and such that we can reliably say an sparse vector can be recovered from observations through . Show your results by making a plot for each method
