I don't understand what you already have, and what you want. The surf() function does not create a 3D array. It creates a 2.5D (two and a half D) perspective rendering of a 2D array. It does not create a 3D (volumetric) array, which would mean that there would be a value for every single (x,y,z) coordinate. So surf() output is not really 3D.
You say you have a 3D pattern already . Exactly what is this? Is it some variable? What does it say when you put this on its own line just after you've created it?
whos my3DPattern % Replace name with the actual name of your variable of course.
And define what a "3d matrix" is. Is that a Y rows by X columns by Z planes volumetric image - an actual 3D array like zeros(rows, columns, planes)? Can you give a small example, like with a 3 by 3 or 5 by 5 array?

What is a data sheet? Do you mean an Excel workbook? If so, what numbers would be in it? And what exactly do you mean by shape? Like the Fourier descriptors? The circularity? Something else? To get the area, you can use regionprops().

thankyou for the answer.I need to get the values of x,y and z coordinates as in an array.Let me try with regionprops()
