Hi everyone, I have a string consisting of e.g. 'y = ca / dy' and wish to solve this symbolically for ca and then calculate ca if I have data for y and dy. I know to do this you would normally type
syms y ca dy
and then use solve. But how can I use syms where y, ca and dy come from a cell array e.g.
inputs = {'y','ca','dy'}
ie something like this i would have thought: syms inputs{1} inputs{2} inputs{3}
Thanks for any help you can provide in this

syms(inputs{1})
%or
syms(inputs{1:2})
%or if you want the entire cell
syms(inputs{:})
