在matlab中从excel中获取数据(fetching data from excel in matlab)

 我试图从excel中获取一个超过17500行的列。现在的问题是，当我在MATLAB中调用它时，它不会给我所有数据的整个矩阵。 它从中间的某个地方获取数据。 
 
 现在真正的问题是我必须在列中添加4个数字并获得平均值，将其保存在另一列中并继续下一组连续的数字并再次重复直到结束。我怎么能在MATLAB中这样做。请发布。帮助我解决这个问题，因为我只是一个菜鸟。 谢谢。 
 
 到目前为止，我所做的是这样的： 
 
clc
g=xlsread('Data.xlsx',1,'E1:E17500');
x=1;
for i = 1:(17500/4) %as steps has to be stepped at 4 since we need avg of 4      
      y{i}=((g{x}+g{x+1}+g{x+2}+g{x+3})/4); 
      x=x+4;
end
xlswrite('Data.xlsx', y, 1, 'F1:F4375');

I am trying to fetch a column from excel with rows more than 17500. Now problem is that when i call it in MATLAB , it does not gives me whole matrix with all data. it fetches data from somewhere in middle.
 
Now the real problem is that i have to add up 4 numbers in the column and get average , save it in another column and proceed to next consecutive set of numbers and repeat again till the end..How could i do that in MATLAB .Please help me solve this problem as i am just a rookie. Thank you.
 
so far i have done is this:
 
clc
g=xlsread('Data.xlsx',1,'E1:E17500');
x=1;
for i = 1:(17500/4) %as steps has to be stepped at 4 since we need avg of 4      
      y{i}=((g{x}+g{x+1}+g{x+2}+g{x+3})/4); 
      x=x+4;
end
xlswrite('Data.xlsx', y, 1, 'F1:F4375');
