MATLAB: Add row/column names to a matrix

colnamescolumn namedatasetprintmatrow name

Hello! I've created a 24 x 12 matrix (24 is dynamic and will change with each .csv file I run through my for loop) and wanted to attach the years (minyear:maxyear) to the rows and months ('Jan' 'Feb' 'March' 'Apr' 'May' 'June' 'July' 'Aug' 'Sep' 'Oct' 'Nov' 'Dec') to the columns. What is the best way to do this? I've tried using colnames and the dataset feature with no success:

M = rand(5)
dataset({M 'FOO','BAR','BAZ','BUZZ','FUZZ'}, ...
                'obsnames', {'ROW1','ROW2','ROW3','ROW4','ROW5'}

Error: Expression or statement is incorrect–possibly unbalanced (, {, or [.

I've also attempted the printrow function

printmat(M, 'My Matrix', 'ROW1 ROW2 ROW3 ROW4 ROW5', 'FOO BAR BAZ BUZZ FUZZ' )

Undefined function 'printmat' for input arguments of type 'double'. Any suggestions? Thanks!

You've missed a bracket

M = rand(5)
dataset({M 'FOO','BAR','BAZ','BUZZ','FUZZ'}, ...
              'obsnames', {'ROW1','ROW2','ROW3','ROW4','ROW5'})

OK, try this code:

clc;    % Clear the command window.
close all;  % Close all figures (except those of imtool.)
clear;  % Erase all existing variables. Or clearvars if you want.
workspace;  % Make sure the workspace panel is showing.
format long g;
format compact;
fontSize = 15;
%===============================================================================

% Get the name of the image the user wants to use.
baseFileName = '1.png'; % Assign the one on the button that they clicked on.
% Get the full filename, with path prepended.
folder = []; % Determine where demo folder is (works with all versions).
fullFileName = fullfile(folder, baseFileName);
%===============================================================================
% Read in a demo image.
grayImage = imread(fullFileName);
% Get the dimensions of the image.
% numberOfColorChannels should be = 1 for a gray scale image, and 3 for an RGB color image.
[rows, columns, numberOfColorChannels] = size(grayImage);
if numberOfColorChannels > 1
  % It's not really gray scale like we expected - it's color.
  % Use weighted sum of ALL channels to create a gray scale image.
  grayImage = rgb2gray(grayImage);
  % ALTERNATE METHOD: Convert it to gray scale by taking only the green channel,
  % which in a typical snapshot will be the least noisy channel.
  % grayImage = grayImage(:, :, 2); % Take green channel.
end
% Display the image.

imshow(grayImage, []);
axis on;

% Enlarge figure to full screen.

MATLAB: Printmat function for unknown number of rows

You can build your headers using SPRINTF; for example:

 >> M = rand(6) ;
 >> vheader = sprintf('ROW%d ', 1:size(M,1))
 vheader =
 ROW1 ROW2 ROW3 ROW4 ROW5 ROW6

(you might want to STRTRIM the output to get rid of the last white space)
