Algorithm (Workflow)

This function, isemptycell, is designed to determine if elements within a cell array are empty. It extends the functionality of the standard isempty function to work with cell arrays.

Input Parameters

• A: A cell array that can contain various types of data, including other cell arrays.

Output Results

• e: A logical array indicating whether each element in the cell array A is empty.

Algorithm Steps

1. Check if the input A is a cell array using iscell(A).
2. If A is not a cell array, use the standard isempty function to determine if A is empty and return the result.
3. If A is a cell array, initialize a logical array e with the same size as A, filled with false.
4. Iterate over each element of the cell array A using a for loop.
5. For each element A{i}, recursively call isemptycell to determine if it is empty.
6. Check if the result ei from the recursive call is a scalar. If not, throw an error indicating a mix of subsets with different sizes.
7. Assign the result ei to the corresponding position in the logical array e.
8. After the loop, return the logical array e.

Example

To use the function, you can create a sample cell array using SGsample(20) and then call isemptycell(A) to check which elements are empty.
