I have generated a mesh in which i extracted a specified node by using findNodes option and i like to extract the that node coordinates and i dont know how.The example code is shared below in which i like to extract the nf2 node coordinates.So, please help me to solve this problem.
clc
clf
model = createpde(1);
importGeometry(model,'BracketTwoHoles.stl');
mesh = generateMesh(model)
[p,e,t] = meshToPet(model.Mesh)
nf2 = findNodes(mesh,'region','Face',1)

If you nave node numbers nd in hand and point of coorsinates p, you can get the points you want using:
iwant = p(nd,:)
