Find string with options (*)

Hi,
I have a cell of strings that I want to see if any of them match a certain string pattern. The string pattern can be something like 'Object(1)=' or Object(123)='. So basically 'Object(*)=' where the asterisk represents a number. Is there a function in Matlab that has a feature that can search strings like that?

expr = 'Object\([0-9]*\)='; %Regular expression
bla = 'asad ca Object(0)= asdas Object(k)=asdObject(1999)='; %string to search
your_idx = regexp(bla,expr); %Returns starting index of matches
Note that you can also get the index of the ending of the matches, the matched strings themselves, etc... For more details please look at:

s='123 sdd5 Object(1)= 25 333sss'
idx=strfind(s,'Object(1)=')
%or
k=123
pattern=sprintf('Object(%d)=',k)
s='123 sdd5 Object(123)= 25 333sss'
idx=strfind(s,pattern)
