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);

then string1 = cell2mat(qc)

syms x y u

q = [x y u]

q =

cellstr(string(q))

ans = 1×3 cell array

{'x'} {'y'} {'u'}
