In matlab, scope of a variable is limited to the function in which is declared. If u want to share the variable between multiple functions, then declare it as 'global' in each function which access it. In your case it should be
push button1
global a;
a = [1 2 3 4];
push button2
glabal a;
xlswrite('a.xlsx',a);
