The code for generating figure 23 is provided.

The file "RIE.py" performs the experiments, and the proposed RIEs are implemented in this file.
The code takes as input the aspect ratio (greater than1), the SNR, and the prior for the matrix X. Matrices Y and W are taken to be Gaussian. To run it, use the following command:
 "python3 RIE.py -a (alpha) -s (SNR) -p (prior: Wigner or Wishart)
The outputs are the MSE of the Oracle, X-RIE.

The outputs are processed in the notebook file to generate the plots.
