Error using MC2Dmex

[Waves-base]

While i try to run propram, i faced follwing error, any suggestions ?

xsize =  10;    % width of the region  [mm]
ysize =  10;    % height of the region [mm]
dh = 1;         % discretisation size  [mm]
vmcmesh = createRectangularMesh(xsize, ysize, dh);

% Create a light source
%    - Set a light source from boundary elements 4 to 7 
%    - Photons are launched at a random angle so that all angles have a cosinic distribution 
vmcboundary.lightsource(4:7) = {'cosinic'};

% Give optical parameters
%    - Constant optical parameters are set troughout the medium.
%    - Alternatively, optical parameters can set be for each element using indexing 

vmcmedium.absorption_coefficient = 0.01;     % [1/mm]
vmcmedium.scattering_coefficient = 1.0;      % [1/mm]
vmcmedium.scattering_anisotropy = 0.9;       % anisotropy parameter g [unitless]
vmcmedium.refractive_index = 1.3;            % refractive index [unitless]

% Run the Monte Carlo simulation
solution = ValoMC(vmcmesh, vmcmedium, vmcboundary);

% Plot the solution using MATLAB 
patch('Faces',vmcmesh.H,'Vertices',vmcmesh.r,'FaceVertexCData', solution.element_fluence, 'FaceColor', 'flat', 'LineWidth',1.5);
