Thu, 31 Jul 2014 16:56:19 GMTR3 (i mean 3D to 3D) function in Matlab? I have found many methods to interpolate function R3->R1 (i mean 3D to 1D), but no possible way to accoplish my task. Except for Thin Plate Splines, they worked fine, but I want something new (if it is possible, Kriging).
"Vq = interp3(X,Y,Z,V,Xq,Yq,Zq) returns... X, Y, and Z contain the coordinates of the sample points. V contains the corresponding function values (SCALAR) at each sample point. Xq, Yq, and Zq contain the coordinates of the query points." This is just what I have mentioned at the beginning. interp3 operate with function (bijection, correspondence) from space with 3 coordinates (3D, triplet) to space with 1 coordinate (1D, scalar). I want to establish and operate with correspondence from 3D to 3D..
TPS solves such problems. http://www.mathworks.com/matlabcentral/fileexchange/37576-3d-thin-plate-spline-warping-function
http://www.mathworks.com/matlabcentral/fileexchange/22227-thin-plate-splines
I used the first link. The interface is pretty straightforward. I marked: 1. points: old positions of control points; 2. ctrlpoints: new positions of control points; 3. object: source template.
But I want Kriging now.
Thank you very much.]]>How to interpolate R3->R3 (i mean 3D to 3D) function in Matlab?

Fri, 25 Jul 2014 20:44:50 GMTI have cell kernels, mostly ellipses
In 200 enlargement is : http://i.imgur.com/sJZYAEc.png
First line: shape is like circle,in 2-nd and 3-rd ellipses horizontal and vertival, next line - ellipses with angles 45 degree.
This shapes must be determine as even.
Next is "kształt trójkątno - sercowaty" it is average even
Next two lines are shapes, which can't be determine as even.

Tue, 08 Jul 2014 12:53:38 GMTWhich is method to symbolic transformations of equations?
For example: I must find equation of line passing through two points (x0,y0) and (x1,y) in form Ax + By + C = 0
this equation is (y-y0)*(x1-x0) = (x-x0)*(y1-y0)
algorithm must change it to (y1-y0)x + (x0-x1)y + y0(x1-x0) + x0(y0-y1)Which is method to symbolic transformations of equations?
