How to make a function generate random outputs using variables with given values?

I have a 3D plot that uses the following equations for x,y,z:

t = linspace(0,2.*pi,1000);
x = 4.*cos(t).*sin(2.*t).*cos(10*t);
y = 7.*sin(t).*cos(3.*t);
z = t;

and the following codes to plot them:

figh = figure;
for k=1:length(t)
    clf
    t_k = t(k);
    x_k = x(k);
    y_k = y(k);
    z_k = z(k);
    plot3(x_k, y_k, z_k, 'gd', 'LineWidth', 2.5, 'MarkerSize', 12)
    hold on
    plot3(0.99*x_k, 0.99*y_k, 0.99*z_k, 'ro', 'LineWidth', 2.5, 'MarkerSize', 10)
    hold on
    plot3(0.98*x_k, 0.98*y_k, 0.98*z_k, 'bs', 'LineWidth', 2.5, 'MarkerSize', 10)
    hold on
    plot3(x, y, z, 'k-', 'LineWidth', 2); 
end

My question is is there any way of producing a designated number of randomly generated outputs using this code? But for example for each output, things such as plot colour, marker appearance, size and width change?

[Voss]

t = linspace(0,2.*pi,1000);
x = 4.*cos(t).*sin(2.*t).*cos(10*t);
y = 7.*sin(t).*cos(3.*t);
z = t;
N = 3;
figh = zeros(1,N);
for v = 1:N
    figh(v) = plot_xyzt(x,y,z,t);
end

function figh = plot_xyzt(x,y,z,t)
marker_size = randi(20,1,3);
line_width = randi(10,1,4);
color = rand(4,3);
marker = 'hop*^svd<>+x.';
marker = marker(randi(numel(marker),1,3));
figh = figure;
for k=1:length(t)
    clf
%     t_k = t(k);
    x_k = x(k);
    y_k = y(k);
    z_k = z(k);
    plot3(x_k, y_k, z_k,'Color',color(1,:),'LineWidth',line_width(1),'MarkerSize',marker_size(1))
    hold on
    plot3(0.99*x_k, 0.99*y_k, 0.99*z_k,'Color',color(2,:),'Marker',marker(2),'LineWidth',line_width(2),'MarkerSize',marker_size(2))
    hold on
    plot3(0.98*x_k, 0.98*y_k, 0.98*z_k,'Color',color(3,:),'Marker',marker(3),'LineWidth',line_width(3),'MarkerSize',marker_size(3))
    hold on
    plot3(x, y, z,'Color',color(4,:),'LineWidth',line_width(4))
    drawnow()
end
