Find which substring is contained in string with Matlab

Question

I have a char variable called "condition". The content of this variable is something like: "21331-54-task-5da1-6256853-35-1-3.mp4".

I need to determine which one of the following characters is contained in the name: 25, 35, 45. I tried with contains(), but this only tells me whether one of these is contained or not in condition. It doesn't tell me which one is contained.

I also tried:

strToFind = {'25', '35', '45'};

pos = strfind(strToFind, condition)

but it gives me the following result:

pos =

1×3 cell array

{0×0 double} {0×0 double} {0×0 double}

Any suggestion on how to solve this? Thank you in advance

Answer 1

~cellfun(@isempty, regexp(condition, strToFind, 'once'))

will give a logical array the same size as strToFind , telling if each of the strings in strToFind is present in condition .

You can also use

cellfun(@(x) contains(condition, x), strToFind)
