reportCellArrays
reportCellArrays reports all expressions that assign or create cell
arrays that are not arrays of character arrays or arrays of
heterogeneous objects. Cell array assignments where the cells are of
unknown type are reported based on a parameter value. Using cell arrays
for for example numbers or logicals is often discouraged because it is
unnecessary, more difficult to read, or because it leads to poorer
performance. By using the fourth preference described in section
Preferences, you can choose whether or not to ignore
cells of unknown datatype for this report. CC4M cannot reliably
determine the datatype of the cell assigned in every case. For the
unknown cases, you can choose whether to report them or not. If this is
set to false, all results that are reported are violations for which
it is certain the assigned cell is not an object nor a character array.
