Hi Chiluveru,

Are you still having trouble with this issue with code generation? Referring to the "cell" documentation:

https://www.mathworks.com/help/matlab/ref/cell.html

"cell" does use bracket-based indexing (for example, myCell{1} will access the first element of the cell array myCell). However, it's still possible there could be an issue with MATLAB or Code Generation. Could you provide a reproduction script so we can generate the same error you are seeing, on our side? Thanks,

Matan

Hi @Chiluveru Manishankar,

If you go through the documentation of cell array it clearly says that we should use curly braces to access the contents of cells.

Parentheses are used to refer to sets of cells, Parentheses are also used for regular array indexing in MATLAB.

To help you understand here is an example script which uses cell array:

load("myCellArray.mat");
function cellArray = doubleCell(cellArray) 
    % Iterate through the cell array and double each numeric element 
    for i = 1:length(cellArray) 
        % Double the numeric array 
        cellArray{i} = 2 * cellArray{i}; 
    end 
end

Kindly refer to the documentation below for more information on Cell Arrays:
