I created a map like this:Instead of using remat, it seems even more convenient and intuitive to start a cell string array like this: C(1:10) = {''} % Array of empty char And the same approach can be used to generate cell array with other data types. C(1:10) = {""} % Array of empty string C(1:10) = {[]} % Array of empty double, same as cell(1,10) But be careful with scalersData Type Conversion.
