"numeric in the sense i want to convert this cell array to a array where my array type is double with same data"
Okay. Please show us the exact numeric value that you expect to get for the character vector 'fh8453655' .

In other words: fh8453655 is not a number. It is not clear, what you expect as output. Perhaps 8453655?

maybe this ?
>> a = {'fh8453655'}
>> beginStr = regexp(a, '\d+', 'match');
>> beginNumbers = cellfun(@(x) str2double(x{1}), beginStr)
beginNumbers =
8453655

Simpler, but equally fragile:
a = {'fh8453655'}
b = str2double(regexprep(a,'\D+',''))
b = str2double(regexp(a,'\d+','match','once'))
