Blank rows are read as nans with xlsread. So use
N(isnan(N))=0

N is the output from xlsread, assuming you have numeric data. See the help for xlsread.

N = xlsread(filename);
Where there is a blank cell in the Excel worksheet, N will be NaN at those locations, and N will have valid numbers at other locations where you have valid numbers in the worksheet. Matt's code changes those matrix locations with NaN's in them from NaN to 0, as you requested. Understand?
