Hello,
I am using Origin 6.1g and wondering which algorithm is used to smooth matrixes (the German menue item is "Matrix - Glätten").
Does anybody know?
Thanks in advance,
Andreas |

Hi Andreas,
The following information is from the Origin Help File:
Smoothing----------------------
Origin does the following:
If either the number of columns or the number of rows in the matrix is less than 32, Origin expands the matrix by a factor of two, then shrinks the matrix by a factor of two. Origin then repeats this process once more.
If either the number of columns or the number of rows in the matrix is greater than 32, Origin shrinks the matrix by a factor of two, then expands the matrix by a factor of two.
For more information, see Shrinking and Expanding.
Shrinking------------------------
Matrix shrinking is a simple averaging of grid points.
Expanding------------------------
Matrix expansion uses a bilinear interpolation method to add the inserted points.
