I am trying to plot and refresh the figure which I created with "tiledlayout"

function out = mtrx_surf(Z3)
persistent srf
if isempty(srf)
    x = 1:30;
    [X30, Y30] = meshgrid(x);
    %Z30 = ones(30);
    Z30 = imresize(Z3,[30 30],"bilinear")';
    tiledlayout(1,2)
    nexttile
    srf = surf(X30,Y30,Z30);
    axis([0 30 0 30 -5 80])
    clim([20 60])
    nexttile
    srf = surf(X30,Y30,Z30);
    shading interp
    axis([0 30 0 30 -5 80])
    clim([20 60])
else
    Z30 = imresize(Z3,[30 30],"bilinear")';
    %    tiledlayout(1,2)
    nexttile
    srf.ZData = Z30;
    axis([0 30 0 30 -5 80])
    clim([20 60])
    nexttile
    srf.ZData = Z30;
    shading interp
    %   axis([0 30 0 30 -5 80])
    %  clim([20 60])
    %puase(0.5)
end
out = 1;
clear surf
end

It turns out that at very first step I am able to create plot with 2 tiles

on the next time as "else" is evaluted then it crashes ... and no plots.

How can I evalute, reset, refresh the same plot when using tiledlayout function to be able to plot multi-charts on the same figure? How can I optimized tehe my function?
