MATLAB: How to convert a sym array into a string array

cell arraysconvertMATLABstringsymbolictable

I have very long arrays of symbolic variables which I need to convert to cell arrays of strings: For example, turning this:

syms x y u
q = [x y u]

into this:

qs = {'x' 'y' 'u'}

something like num2string() but with syms? I'd appreciate any help, thanks.

qc = arrayfun(@char, q, 'uniform', 0);

strjoin(A)

will create a character array.

string(strjoin(A))

will create a string.

Something like this

A = {'Hello B Hi A Where is D?'};
B = strsplit(A{:}, ' ')';

Result:

B =
  7×1 cell array
    {'Hello'}
    {'B'    }
    {'Hi'   }
    {'A'    }
    {'Where'}
    {'is'   }
    {'D?'   }
