Algorithm (Workflow)

This function, cell2array, is designed to convert a cell array with rows of varying lengths into a 2D array with a consistent number of columns. The function is part of the SolidGeometry library and was introduced in version 2.1. It may be considered obsolete due to the existence of cell2mat.

Input Parameters

• C: A cell array where each cell contains a row of numbers. The rows can have different lengths.

Output Results

• A: A 2D array where each row corresponds to a cell in C. The number of columns is equal to the length of the longest row in C. If a row in C is shorter than the longest row, the remaining elements in that row of A are filled with NaN.

Algorithm Steps

1. Determine the number of rows, n, in the cell array C using size(C,1).
2. Initialize a variable m to zero. This will store the maximum row length found in C.
3. Iterate over each row i in C to find the maximum row length:
   • For each row C{i}, determine its length k using size(C{i},1).
   • Update m to be the maximum of its current value and k.
4. Create an n by m array A filled with NaN using nan(n,m).
5. Iterate over each row i in C again to populate A:
   • Determine the length k of the current row C{i}.
   • If k is greater than zero, copy the elements of C{i} into the first k columns of the i-th row of A.
