Dear all,
I have
A={'BARI 500G' ...
'DUR NOR 18CONmS' ...
'SENSO NORM ST-TUB 75ML '...
'MARL 100S 20CIG'...
'BI BOY WHI RMAL DU NA 15 SK'...
'REGU KR GRA ME FAMIAL 1000 ST GRND'
};
I was wondering if there is a way to choose the numbers from A. In case i have 2 numbers in a string I want to select the second one
For instance,
B=[500 18 78 20 15 1000]

@Antonet: Do you need those numbers as a vector??

B = regexp(A,'\d*','Match');
returns one result for each number found in each string. You will then have to get the last value of each cell and convert it to an array (using str2double)

Perfect!

Luffy on 10 Jul 2012
C = regexp(A,'[0-9]','match');
disp(C)
So do you need to just display those numbers/return them as a vector

If you want a vector, what do you want for if there is no match for a particular line of the string?

To whom it may concern:
I have the numbers below in a 1x1 string. How do I seperate them into seperate rows or columns? I want all the numbers between ";" (semi-colons).
Any assistance would be greatly appreciated.
