Algorithm (Workflow)

This function, cell2class, is designed to convert a cell list of elements of the same class into an array of that class. It is particularly useful when dealing with MATLAB's get command, which often returns cell lists that cannot be directly processed by class methods.

Input Parameters

• cells: A cell list containing elements of any class type. The function assumes that all elements within the cell list are of the same class.

Output Results

• x: An array of the same class type as the elements within the input cell list.

Algorithm Steps

1. Determine the size of the input cell list cells using the size function and store it in n.
2. Initialize the output array x using repmat to replicate the first element of cells across the dimensions specified by n. This ensures that x is of the same class type as the elements in cells.
3. Iterate over each element in the cell list using a for loop. The loop runs from 1 to the total number of elements in x, as determined by numel(x).
4. Within the loop, assign each element from cells to the corresponding position in x. This effectively converts the cell list into an array of the same class type.

Example Usage

The function can be used in a scenario where graphical objects are manipulated:

SGfigure; 
CPLplotasPS(CPLsample(14)); 
h=findobj(gca,'type','polygon');
a=get(h,'Shape'); 
x=cell2class(a);
cla; 
plot(x); 
shg;

In this example, graphical objects of type 'polygon' are found and their shapes are retrieved as a cell list. The cell2class function then converts this list into an array, which can be plotted directly.
