Hi
I am wondering whats wrong with this code:
filtered=(min_tabell(strcmp(min_tabell.best_salt_1_n_best_salt_2,'NH4Cl',:)||(strcmp(min_tabell.best_salt_1_n_best_salt_2,'NaCl',:))))
the error that I get
Undefined function or variable 'strcmp'.

Just a guess, since I have no idea what your array content or size are.
strcmp() takes two arguments, but you're feeding it two arguments while simultaneously trying to index into it like an array.
things = {'b','a','NH4Cl'}
things = 1×3 cell array
{'b'} {'a'} {'NH4Cl'}
filtered_ok = strcmp(things,'NH4Cl')
filtered_ok = 1×3 logical array
0 0 1
filtered_bad = strcmp(things,'NH4Cl',:)
Unrecognized function or variable 'strcmp'.
If you're trying to select all columns of the selected rows in min_tabell, then do that outside the calls to strcmp().

No, maybe I shd have written wht the code was supposed to do: Filtered is a table that comes out after I have used strcmp in two conditions on min_tabell n then the question is whether it can be done with "or" symbol? Whether strcmp can be used two times including an "or" symbol
