I have a file with non standard format and i want to read specific parts of it, that consist of real or integer numbers.
str1='N.ELBETI.150.L10';
str2='KARDIA_3.150.L20';
str3='axeloos1.15.75.L20';
str4='florina2.6.3.L2.1';
i just want to store the numbers in the central part and at the end of each string, i.e.:
150 and 10 from str1, 150 and 20 from str2, 15.75 and 20 from str3, 6.3 and 2.1 from str4 i have tried several ways but i cannot. Can you help me ?
An alternative to the already posted, nice answer. Apply the following function to each string.
function [num1, num2] = extract_from_string(s)
num1 = str2num(s(find(s == '.',1,'first')+1:find(s == 'L',1,'first')-2));
num2 = str2num(s(find(s == 'L',1,'first')+1:end));
end
Use regexp like this:
To obtain the first number:
str1(regexp(str1,'\.\d')+1:regexp(str1,'L\d')-2)
To obtain the last number:
str1(regexp(str1,'L\d')+1:end)
These commands also work for the other strings
str1 to str2/str3/str4 in every part od the command (the first command has 3 str1+1: str1(regexp(str1,'L\d'):end)
