xlswrite() problem with writing file

 function [ A ] = SaveFile( B )
A=[];
for i=1:size(B,1)
if sum(B(i,:))>10
    A=[A;B(i,:)];
end
end
notepad=[pwd '\asd.txt']; %no problem in saving
excellZad=[pwd ' \asdexcel.xlsx' ];
save (notepad, 'A','-ASCII');
xlswrite (excellZad, A);
end

 B=[1 2 3; 4 5 6; 7 8 9;10 11 12; 13 14 15; 16 17 18];
SaveFile(B);

This is the error

You have a space in the folder that you probably don't want:

excellZad=[pwd ' \asdexcel.xlsx' ];  % Space before the \

Instead, try fullfile():

excellZad = fullfile(pwd, '\asdexcel.xlsx');

Also make sure that some old version of the file is not already open in Excel when you call xlswrite().
