The code for generating figure 26 is provided.

The file "RIE.py" performs the experiments, and the proposed RIEs are implemented in this file.
The code takes as input the dimension M less than N=2000. Prior of Y is Gaussian, and 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 -M "
The outputs are the MSE of the Oracle and Y-RIE.

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