-Both programs plot the distributions of the eigenvalues of the given `A(N,s,m)` for input variables `N`,`s,m` on the plane.
+Both programs plot the distributions of the eigenvalues of the given `A(N,s,m)` for input variables `N,s,m` on the plane.
 When `m` equals `1` then `A(N,s,m)` is the same matrix as the matrix `A(N,s)`.
