行と列のラベルを使用してマトリックスを表示する

Matlabターミナルで行と列のラベルを持つマトリックスを表示する便利な方法はありますか?このようなもの:

M = Rand(5);
displaymatrix(M, {'FOO','BAR','BAZ','BUZZ','FUZZ'}, ...
                 {'ROW1','ROW2','ROW3','ROW4','ROW5'});    %??

降伏:

        FOO       BAR       BAZ       BUZZ      FUZZ
ROW1    0.1622    0.4505    0.1067    0.4314    0.8530
ROW2    0.7943    0.0838    0.9619    0.9106    0.6221
ROW3    0.3112    0.2290    0.0046    0.1818    0.3510
ROW4    0.5285    0.9133    0.7749    0.2638    0.5132
ROW5    0.1656    0.1524    0.8173    0.1455    0.4018

さらに良いのは、ASCIIアートの優れた機能を備えたものです。

     |   FOO       BAR       BAZ       BUZZ      FUZZ

Matlabには、Control Systemsツールボックスにprintmatという関数があります。これは「ctrlobsolete」ディレクトリにあるため、「廃止された」と見なすことができますが、それでも機能します。

ヘルプテキストは次のとおりです。

>> help printmat
 printmat Print matrix with labels.
    printmat(A,NAME,RLAB,CLAB) prints the matrix A with the row labels
    RLAB and column labels CLAB.  NAME is a string used to name the 
    matrix.  RLAB and CLAB are string variables that contain the row
    and column labels delimited by spaces.  For example, the string

        RLAB = 'alpha beta gamma';

    defines 'alpha' as the label for the first row, 'beta' for the
    second row and 'gamma' for the third row.  RLAB and CLAB must
    contain the same number of space delimited labels as there are 
    rows and columns respectively.

    printmat(A,NAME) prints the matrix A with numerical row and column
    labels.  printmat(A) prints the matrix A without a name.

    See also: printsys.

例:

>> M = Rand(5);
>> printmat(M, 'My Matrix', 'ROW1 ROW2 ROW3 ROW4 ROW5', 'FOO BAR BAZ BUZZ FUZZ' )

My Matrix = 
                       FOO          BAR          BAZ         BUZZ         FUZZ

         ROW2      0.90579      0.27850      0.97059      0.42176      0.03571

データには何らかの構造があるように見えるので、より構造化されたクラス- dataset 、Statisticsツールボックスの一部に入れることができます。

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

            FOO        BAR         BAZ        BUZZ         FUZZ    
    ROW1    0.52853     0.68921    0.91334     0.078176     0.77491

これは古い投稿であることは知っていますが、解決策は array2table 。具体的には、OPの場合、単純に次のようにします。

>> M = Rand(5);
>> names= {'A','B','C','D','E'}; 
>> array2table( M, 'VariableNames', names, 'RowNames', names )

ans = 

            A          B          C          D          E    
         _______    _______    _______    _______    ________

                num2cell(Rand(5))))

Matthew Oberhardt、便利なコード、マトリックスに名前を追加しました。ここでは新しいコードがもう1つ変数を追加しただけです。また、使用例を見てみましょう。convはmxnマトリックスです。

- - - - - - - -コード - - - - - - - -

function out = dispmat(M,name,row_labels,col_labels);
%% Matthew Oberhardt

% intended to display a matrix along with row and column labels. 
%% ex:
% M = Rand(2,3);
% row_labels = {'a';'b'};
% col_labels = {'c 1','c2 ','c3'};
% % if there are no labels for rows or cols, put '' as the input.
% row_labels = '';

%Modified 14.07.2014
%Nestor Cantu
%Added the name of the matrix.

%% check that the row & col labels are the right sizes
[nrows,ncols] = size(M);

%% populate if either of the inputs is empty 
if isempty(row_labels)
row_labels = cell(1,nrows);
    for n = 1:nrows
        row_labels{1,n} = '|'; 
    end
end
if isempty(col_labels)
    col_labels = cell(1,ncols);
    for n = 1:ncols
        col_labels{1,n} = '-';
    end
end

assert(length(row_labels)==nrows,'wrong # of row labels');
assert(length(col_labels)==ncols,'wrong # of col labels');

row_labels = reshape(row_labels,1,length(row_labels));
col_labels = reshape(col_labels,1,length(col_labels));

%% remove spaces (since they are separators in printmat.m

%% create labels, space delimited
c_out = [];
for n = 1:length(cols)

end
c_out = c_out(1:end-1);
r_out = [];

役に立つかもしれないコードをいくつか書きました-'printmat'関数を使用しますが、入力を変更して、列および/または行ラベルを含むセルベクトルにします。お役に立てば幸いです。
