remove cell in matlab

To remove a cell in MATLAB, you can use the cellfun function. For example, consider the following cell array:

main.m
cellArray = {'one', 'two', 'three', 'four', 'five'};
53 chars
2 lines

To remove the second cell 'two' from the cell array, you can use the following code:

main.m
cellArray(2) = []; % removes the second cell
45 chars
2 lines

After executing this code, the cell array cellArray will be:

main.m
{'one', 'three', 'four', 'five'}
33 chars
2 lines

Alternatively, if you want to remove a cell based on its content or a specific condition, you can use the cellfun function with a function handle that returns a logical value. Here's an example:

main.m
cellArray = {'one', 'two', 'three', 'four', 'five'};
cellToRemove = 'two';
idx = cellfun(@(x)isequal(x,cellToRemove),cellArray);
cellArray(idx) = [];
150 chars
5 lines

After executing this code, the cell array cellArray will be:

main.m
{'one', 'three', 'four', 'five'}
33 chars
2 lines

Here, the cellfun function applies the anonymous function @(x)isequal(x,cellToRemove) to each cell of the cellArray, which checks whether the content of the cell is equal to the cellToRemove variable. The result is a logical index idx that is true for the cells that need to be removed. Finally, the cells with a true index are removed from the cell array.
