I want to change a name with a number in it to the number of the participant.

Hello,

I want to give a number to a participant of my experiment. The number is in it's name, for example: Participant ='AG_1100 02_Porti_29'. The number of the participant is in bold, but I want Matlab to change it to 02 or just 2. So that the result is: Participant = 02.

How can I do this?

What is the rule about what number should be extracted? Is it always at the same offset in the character vector? Is it always the first 2 digits after the first blank? Is it always the first group of digits after the first blank, no matter how many digits that is?

I have like 18 participants, so the number: 02 has to be extracted and is always on that place. There is no blank as you can see in the code.

Participant ='AG_110002_Porti_29'

Participant = str2double(Participant(8:9));
