Algorithm (Workflow)

This function, CPLcellofNaN, is designed to convert a CVL (Closed Vertex List) or CPL (Closed Polygon List) that is separated by NaN values into a cell list. The function is part of the SolidGeometry library and was introduced in version 3.9.

Input Parameters

CVL: A Closed Vertex List or Closed Polygon List that is separated by NaN values. This list is the primary input to the function.

Output Results

VLcell: A cell list where each cell contains a separated part of the input CVL/CPL. Each part is processed to remove NaN separators and is stored as an individual element in the cell array.

Algorithm Steps

The function begins by determining the number of separate parts in the input CVL using the separateNaN function. This function counts the number of NaN-separated segments in the input list.
A cell array, VLcell, is initialized with a size equal to the number of segments determined in the previous step.
A loop iterates over each segment index from 1 to n (the number of segments).
Within the loop, for each segment index i, the function separateNaN(CVL, i) is called to extract the i-th segment from the input CVL.
The extracted segment is then processed by the PLofCPL function, which likely converts the segment into a specific format or structure.
The processed segment is stored in the i-th position of the VLcell array.
After the loop completes, the VLcell array, now containing all processed segments, is returned as the output of the function.

This function is useful for handling lists that are separated by NaN values, allowing for easy manipulation and processing of each individual segment.
