So I have a string in the following format:

filename = "Delft_2_220_20_4344-5088.csv" ;

And I want to extract the numbers from it, what is a good way to do this?

So the result is something like this:

a=2; b=220; c=20;d=[4344 5088];

Read about regexp

>> S = 'Delft_2_220_20_4344-5088.csv';
>> V = str2double(regexp(S,'\d+','match'))
V =
           2         220          20        4344        5088

Using indexing to allocate those values to whatever other variables you want.

+1 Stephen, also if the string contains decimals then

regexp(s,'\d+[\.]?\d*','match')

Thanks Stephen, works perfectly!
