Hi everybody,

how can i set two conditions in one line in the regexp function of matlab? E.g. my input string array is:

str = {'strawberry/banana#(';'apple#,melon*cherry';'apple_banana_cherry'};

I only want to get the starting index of strings that 1. start with 'apple' and 2. end with 'cherry'. In this case it wold be the second and third string of which i'd like to get the index number.

Thanks in andvance!
