    %% Control Placement of Markers Along Line
% Create a line plot with 1,000 data points, add asterisks markers, and
% control the marker positions using the |MarkerIndices| property. Set the
% property to the indices of the data points where you want to display
% markers. Display a marker every tenth data point, starting with the first
% data point.

x = linspace(0,10,1000);
y = exp(x/10).*sin(4*x);
plot(x,y,'-*','MarkerIndices',1:10:length(y))
