split - Convert matlab symbol to array of products -

can convert symbol product of products array of products?

i tried this:

syms b c d; d = a*b*c; factor(d);

but doesn't factor out (mostly because isn't factor designed do).

ans = a*b*c

i need work if b or c replaced arbitrarily complicated parenthesized function, , nice without knowing variables in function.

for example (all variables symbolic):

d = x*(x-1)*(cos(z) + n); factoring_function(d);

should be: [x, x-1, (cos(z) + n)]

it seems string parsing problem, i'm not confident can convert symbolic variables afterwards (also, string parsing in matlab sounds tedious).

thank you!

use regexp on string split based on *:

>> str = 'x*(x-1)*(cos(z) + n)'; >> factors_str = regexp(str, '\*', 'split') factors_str =      'x'    '(x-1)'    '(cos(z) + n)'

the result factor_str cell array of strings. convert cell array of sym objects, use

n = numel(factors_str); factors = cell(1,n); %// each cell hold sym factor n = 1:n     factors{n} = sym(factors_str{n}); end
