How do you search a file for a matching string?

Hi,

I have a huge contacts list in a excel file which consists of following fields

FirstName LastName UserID EmailAddress.

I have FirstName and LastName in MATLAB as a variable.

How do I extract the user ID and EmailAddress for a corresponding FirstName and LastName?

Note:There are some 50,000 contacts in Excel file.

[num,text,v]=xlsread('yourfile')
s1='firstname';
s2='lastname';
idx=find(strcmp(v(:,1),s1) & strcmp(v(:,2),s2)
Id=v(idx,3)
Email=v(idx,4)
