WebMar 20, 2024 · Thanks for your answer. Yes, I see it could potentially have multiple solutions. It is interesting that Matlab orders the struct as it does, though. I would have guessed that it would make a struct sol.1 which contained a vector (x1,y1) for the first solution and a sol.2 with a vector (x2,y2) for the second solution. WebJan 27, 2014 · 3 Answers Sorted by: 12 You can use CELLFUN for this. hits = cellfun (@ (x)strcmp (x.s.text,'Pickabo'),mylist); filteredList = mylist (hits); However, why do you make a cell of structs? If your structs all have the same fields, you can make an array of structs. To get the hits, you'd then use ARRAYFUN. Share Improve this answer Follow
