This error can be resolved by always assigning the variable "out.date", even when data is empty. When data is empty, you should assign "out.date" to a default value, such as an empty cell array. When data is not empty, assign it as usual. Additionally, for better compatibility with MATLAB Coder, it is recommended to store "length(data)" in a variable before using it in a loop. Here is how you can structure your code:
if ~isempty(data) N = length(data); date = cell(N,1); for i = 1:N date{i,1} = data{i,1}; end out.date = date;else out.date = cell(0,1);end
