Martin Diehl 64764b0902 introduced moving of multiple seeds at the same time
introduced more suitable check for convergence of the first bin. Improvements in bringing seeds with a size outside the range of the target closer are no longer invisible
2015-04-14 12:42:35 +00:00
Philip Eisenlohr 790aa32b1b fixed string to character splitting of weight column label 2015-04-13 20:24:03 +00:00
Philip Eisenlohr 4bcc80911e changed grid to float from (wrong) integer type.
row and column probability density normalization now takes place BEFORE limiting data range.

Haiming Zhang 976647b9e4 add the convergence criterion, the method is :
1. calculate the L2 norm of the residual of all the stress points
2. store the relative errors of the L2 norm
3. if the standard deviation of the relative errors of last five fittings is less than 0.05, that it is considered that the relative errors is stabilized, so the fitting is finished.
