Compiling features from regionprops with its filename

I am working on extracting features on my images and compiling the features into one file. I want to put the file name under that file too but it only display the name and it's in 'char'.

My code:

files = dir('*_cell.bmp'); %the folder has 5 images with this extension
[m1 n1] = size(files);
Feature = [];
for i = 1:m1
    x1 = files(i).name;
    [path, name, extension] = fileparts(x1);
    OriginalImage = imread(x1);
    Blue = OriginalImage(:,:,3);
    binaryImage = Blue > 0.1;
    CellMeasure = regionprops(binaryImage,'all');
    CellArea = CellMeasure.Area;

      Feature = [Feature; name CellArea];
end

Output: - on the Workspace, >> Feature 5x10 char

>> Feature

Feature =

0201_cell
0205_cell
0206_cell
0401_cell
4101_cell

Please help.

Before:

Feature = cell(m1, 2);

In the loop:

Feature(i,:) = {name CellArea};

It works! Thanks Walter! What if I have more features? I do this:

files = dir('*_cell.bmp'); 
[m1 n1] = size(files);
Feature = cell(m1,2);
for i = 1:m1
    x1 = files(i).name;
    [path, name, extension] = fileparts(x1);
    OriginalImage = imread(x1);
    Blue = OriginalImage(:,:,3);
    binaryImage = Blue > 0.1;
    CellMeasure = regionprops(binaryImage,'all');
    CellArea = CellMeasure.Area;
    CellPerimeter = CellMeasure.Perimeter;
    ShapeFeat = [CellArea CellPerimeter];

      Red = OriginalImage(:,:,1);
      Green = OriginalImage(:,:,2);
      RMean = mean(Red(:));
      GMean = mean(Green(:));
      BMean = mean(Blue(:));
      ColorFeat = [RMean GMean BMean];

      AllFeat = [ShapeFeat ColorFeat];

      Feature(i,:) = {name AllFeat};
  end

...and it returns

>>Feature
Feature =
    '001_cell'    [1x16 double]
    '002_cell'    [1x16 double]
    '003_cell'    [1x16 double]

How do I expand all the features (in this case, 16) under 'Feature' so that I can save it in an excel file later?

filename = 'M3_Cell.xlsx';
xlswrite(filename,Feature);

[Walter Roberson]

Feature(i,:) = [name num2cell(AllFeat)];

This assumes that AllFeat will be strictly a row vector of numeric values. If that is not the case then you would have to construct, for example,

{name RMean CellMeasure.PixelIDList}
