The code for generating figure 25 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 than 1), the SNR, and the prior for the matrix Y. Matrix X is a shifted Wigner matrix with c=3, and W is a Gaussian matrix. To run it, use the following command:
 "python3 RIE.py -a (alpha) -s (SNR) -p (prior: Gaussian or Uniform)
The outputs are the MSE of the Oracle and Y-RIE.

The root for q_4 is computed in the Mathematica file.

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