Display the Vertex and Triangle labels on the plot

Hello, As in 2D data we can label the vertex and triangle through the code : triplot(dt);

    %Display the Vertex and Triangle labels on the plot

>>vxlabels = arrayfun(@(n) {sprintf('P%d', n)}, (1:10)');
>>Hpl = text(x, y, vxlabels, 'FontWeight', 'bold', 'HorizontalAlignment',...
           'center', 'BackgroundColor', 'none');
>>ic = incenters(dt);
>>numtri = size(dt,1);
>>trilabels = arrayfun(@(x) {sprintf('T%d', x)}, (1:numtri)');
>>Htl = text(ic(:,1), ic(:,2), trilabels, 'FontWeight', 'bold', ...
      'HorizontalAlignment', 'center', 'Color', 'blue');
>>hold off

       How can i label it for 3d points?

text() can take x, y, z coordinates.

i modify the above code for x,y and z as:

vxlabels = arrayfun(@(n) {sprintf('P%d', n)}, (1:20)');

Hpl = text(x, y,z, vxlabels, 'FontWeight', 'bold', 'HorizontalAlignment',...

'center', 'BackgroundColor', 'none');

ic = incenters(dt);

numtri = size(dt,1);

trilabels = arrayfun(@(z) {sprintf('T%d',z)}, (1:numtri)');

Htl = text(ic(:,1), ic(:,2), ic(:,3), trilabels, 'FontWeight', 'bold', ...

'HorizontalAlignment', 'center', 'Color', 'blue');

Doing so i am points labelled properly but the triangles are not labeled properly
