Read in File with Letter, Number, and Quotation Marks

Hi All,
I am trying to read in a data file that contains letters, numbers, and quotation marks (see below):
A = [1, 2, 3, 4; 5, 6, "NaN", 7; 8, 9, 10, 1]
I have done some testing using 'textscan' and am able to read in a file similar to the one above except without the quotation marks. It seems that the punctuation is tripping 'textscan' up. Is there are better way to read in the file without have to do any pre-processing?
cheers, Sean

f=fopen('Your_File','r');
Readings=fscanf(f,'c',[1,inf]);
then change the contents of (Readings) either to numbers using
Contents(i)=str2double(Readings(m:n))
where m:n indicates start:stop of the field, i indicates the place of the matrix storing the number (if needed); or leave it as char as
Content_char=Readings(m:n)
