All your values in the ‘A1.xls’ file are zero.
That will be a problem for ranksum.
D = xlsread('Matlab A1.xls');
Dmin = min(D)
Dmax = max(D)
Dinf = D(~isfinite(D))
Dmin =
0 0 0 0 0 0
Dmax =
0 0 0 0 0 0
Dinf =
0×1 empty double column vector

Please read the documentation on the ranksum function, and consult a statistics textbook on the Wilcoxon rank sum test.
