function [precoders, snrsDb] = getComputedPrecoders(simFolderName, caseNr)
%
% GETCOMPUTEDPRECODERS Load the precoders previously optimized and stored
% in a folder.
%
%     Inputs:     str simFolderName = name of the sim folder with precoders
%                 scalar caseNr = number of the case of interest in that folder
%     Outputs:    cell array precoders = precoder matrices
%                 cell array snrsDb = SNR values
