Numerical universality test. (a) Architecture depiction (left column) and optimization objective function (right column) for 100 target matrices at various values of M and N. Black boxes denote any possible realization for the F matrix. (b) Multiple trials for $N=8$ and $M=9$ using 250 random F matrices were considered; 250 targets were used for each matrix F. Shown is the distribution of the number of LMA runs to achieve a norm lower than the stopping norm of ${10}^{-10}$, with a maximum of 50 iterations per run. (c) Norm (log$_{10}^{}$) in terms of the number of iterations for the run with the best norm. Using 100 random matrices F, each with a single target matrix.
