I want to have my 3D meshed model plot scaled to a certain size. Are there any functions that can do? I am actually a rookie in Matlab. Please kindly do me a favor.Thanks a lot.

Hi Patrick,
What do you meany you want to make it bigger or smaller in proportion?!
You want to stretch it in X and not in Y for instance?
If so then mulyiply X data to a constant grater than 1.
Let me know exactly what we're talking about.
Tnx

Patrick, cant you multiplu the whole x,y,z dimensions of the model by a constant?!
data = data.*10;
For example above will make it 10 times bigger

Thank you! I've done it. Sorry that I am really a beginner in Matlab and asking such a simple question. Do appreciate your help!

Another technique you should know about (although it might be overkill for this purpose) is hgtransform. This creates an object which you parent your mesh to. This object has a Matrix property you can use to scale, rotate, and translate your mesh:
g = hgtransform
surf(peaks,'Parent',g)
set(g,'Matrix',makehgtform('scale',10))
If you do help on makehgtform, you'll find all of the different transformations you can do with this.
This approach can be very helpful when you have more than one mesh and you're trying to place them relative to each other.
