How to append in a excel file using Matlab?

Imagine that I have the following excel file called "algoperformace.xls"

algoName	mode	95percentile	max	mean
Algorithm1	13.15153679	20.03323188	39.52043729	15.65858

Now, I would like to add a new line as the following into this excel file using matlab

Neighbor

2.721678458

5.536962451

26.63633753

3.858783

How to do that?

Answer:
%% Loading the excel into matlab

[~, ~, alldata] = xlsread('algperformace.xls');
% We will add new entry line into 'alldata' variable and then will write the excel file
% The script will compute the value for algoname, mode, color_diff_95_percentile, max, mean
% adding those values into the cell of 'alldata'
alldata(size(alldata,1),:)={algoname, mode, color_diff_95_percentile, max, mean};
%writing the complete new 'alldata' into the same excel file
xlswrite('algperformace.xls', alldata);
