node creation using for loop

how can we create nodeset having data like node_number, x,y,z coordinates say for 20 nodes using for loop

Attach your data.

[Shahrukh s]

node_number = 1:20

x = 100:120

y =10:20

z = 0

You cannot have 20 nodes for given x and y. You will have more number of nodes. Check the links given in the answer.

What do you want to do with this data once you've chosen the "best" data structure to store your nodeset? Plot it? Connect nodes into a network graph? Something else?

[Shahrukh s]

i just want a for loop programme to execute this type data structure

[KSSV]

x = 100:120 ; 
y =10:20 ; 
[X,Y] = meshgrid(x,y) ; 
mesh(X,Y)

Try using graph() object provided by MATLAB: https://www.mathworks.com/help/releases/R2020a/matlab/ref/graph.html. For example,

node_ID = string(1:20);
x = rand(20,1);
y = rand(20,1);
z = rand(20,1);

G = graph(zeros(20), node_ID);
G.Nodes.x = x;
G.Nodes.y = y;
G.Nodes.z = z;

plot(G)
