Writing results in excel from matlab

I need to write a string value in an excel cell, followed by array values of A and B (each value in a different cell) like in the figure. But when I try the following code, only string is written and numeric values are lost. Any help appreciated.

 function_name = 'F2';
  A={[1 2 3 4]};
  B= {[ 5 6 7 8]};

filename = 'testtest.xlsx';
xlswrite(filename,[{Function_name},A B])

F = 'F2';
A=[1 2 3 4];
  B= [ 5 6 7 8];
filename = 'testtest.xlsx';
xlswrite(filename,[{F} num2cell(A) num2cell(B)])
