scripts default iconTable Breakpoint Optimization (Scripts) Publisher's description

Two simple functions for optimizing breakpoint placement of 1D and 2D tables.

Two simple functions for optimizing breakpoint placement of 1D and 2D tables.
Given an input 1D or 2D table and a desirable number of breakpoints, these functions will calculate the best placement of the breakpoints to fit the input table. The user can specify how the table values should be interpolated using linear, cubic, nearest methods, etc. The breakpoints, new table, and mean squared error of the fit are returned.

The optimal placement of breakpoints is taken to be the placement resulting in the minimum mean squared error of the new table evaluated at the original table's breakpoints with the specified interpolation scheme. For regularly sampled input tables, this acts as an integral of error over the table's area. This allows irregular sampling of the original table to focus on critical (e.g., rapidly changing) areas of the table.

Requires the Optimization Toolbox(TM).

No special requirements.
