Assigment error in a sym-to-char conversion

Hi,

I need to convert a 4x4xN symbolic matrix (called T) in a char, so, after initialization by

Tchar = char(zeros(4,4,N));

so I use a for loop with three indices (ii,jj,kk) as:

for ii=1:N

    for jj=1:4
      for kk=1:4
        Tchar(jj,kk,ii) = char(T(jj,kk,ii));
      end
    end
  end

but it returns me the error..:

Assignment has more non-singleton rhs dimensions than non-singleton
subscripts

but T-dimensions is equal to Tchar dimensions. What is the matter?

If T is a symbolic matrix, changes are that the character representation of each entry is not exactly one character per entry, but you attempt to assign the character version of the entry to a single character location Tchar(jj,kk,ii).

I suggest

Tchar = cell(4,4,N);

and

Tchar{jj,kk,ii} = char(T(jj,kk,ii));   %notice {}

Thanks!
