A = {'jdldi'; 'jdks5.4555h'; 'f67'}
b=regexp(A,'\d+(\.)?(\d+)?','match')
out=str2double([b{:}])

A1 = regexp(A,'[\d*\.]*\d*','match')
A2 = [A1{:}]
out = str2double(strcat(A2{:}))
A simple version:
A = {'jdldi'; 'jdks5.4555h'; 'f67'}
S = cat(2, A{:});
S(isletter(S)) = [];
The simpler the code, the less chances to insert a bug.

Thanks Jan! I wasn't aware of the isletter function
