    Generate and visualize the random placement of wireless nodes within a rectangular area. Using the nodePositionRandom function, you distribute ten nodes uniformly inside a 100-by-100 meter region. Then, a wirelessNetworkViewer object displays the resulting node positions.

    Set the area dimensions and number of nodes.

    areaLength = 100;           % Rectangle length (meters)
areaWidth = 100;            % Rectangle width (meters)
numNodes = 10;              % Number of random nodes

    Generate random node positions in the rectangle.

    [nodePositions,rectPoly] = nodePositionRandom( ...
    "rectangle",[areaLength areaWidth],NumNodes=numNodes);

    View the positions using the wireless network viewer.

    viewer = wirelessNetworkViewer(CanvasSize=[200 200]);
addNodes(viewer,nodePositions,Type="RandomNodePositions")

    Show the rectangle boundary.

    showBoundary(viewer, ...
    Position=[0 0 0], ...
    BoundaryShape="rectangle", ...
    Bounds=[areaLength areaWidth], ...
    Name="RectangleBoundary")

    Figure Wireless Network Viewer contains an axes object. The axes object with xlabel X-axis (m), ylabel Y-axis (m) contains 22 objects of type line. One or more of the lines displays its values using only markers These objects represent Canvas Boundary, RandomNodePositions, Boundary.

    Remove the node position by uncommenting this line of code.

    % removeNodes(viewer)

    Hide the rectangle boundary by uncommenting this line of code.

    % hideBoundary(viewer)

    Input Arguments
