You could be a bit more explicit in the call to legend:
txt = ['lambda = ',num2str(lambda(check))];
ph = plot(1:100, abs(Arec(:,2000))); % ,'DisplayName',txt); % capon
leg_str = sprintf('lambda = %3.3g',lambda(check));

True, but explicitly calling legend with the plot-handles has additional benefits in terms of what to include, which is not necessary in this case but will eventually pop up.
