I am using R2018b, and trying to use the function 'validtaestring', but it doesn't find a partial match. Has anyone tried that in this version?

STR2={'AA_UCECC'};
str='UCE';
validatestring(str,STR2)
Expected input to match one of these values:
'AA_UCECC'
The input, 'UCE', did not match any of the valid values.

Seems like validatestring only searches first n characters. Therefore I am using strfind.
Thank you,

strfind returns an index or an empty null string.
You might want to use contains() like I did in my answer, unless you really need to know the index where the substring starts. If you have just one item, like you did, then you can also use strcmp() or ismember().

To find partial matches, don't use validatestring(). Use contains
validString = contains(str, STR2);
