Pantalla de matriz con rótulos de fila y columna

Matlab dispone de una función llamada printmat en los Sistemas de Control de la caja de herramientas. Es en el directorio «ctrlobsolete«, por lo que podemos asumir que es considerado como «obsoleto», pero todavía funciona.

El texto de ayuda es:

>> 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.

Ejemplo:

>> 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

Parece que los datos tienen una estructura de modo que usted puede poner en una forma más estructurada de la clase – un conjunto de datos, parte de las Estadísticas de la caja de herramientas.

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

ans = 
            FOO        BAR         BAZ        BUZZ         FUZZ    
    ROW1    0.52853     0.68921    0.91334     0.078176     0.77491
    ROW2    0.16565     0.74815    0.15238      0.44268      0.8173
    ROW3    0.60198     0.45054    0.82582      0.10665     0.86869
    ROW4    0.26297    0.083821    0.53834       0.9619    0.084436
    ROW5    0.65408     0.22898    0.99613    0.0046342     0.39978

De forma alternativa, si la publicación de su salida, aquí es un ejemplo de varias funciones que llevará a una matriz w/row,col nombres y producir un html en formato de tabla.

Sé que este es un viejo post, pero creo que la solución es el uso de array2table. Específicamente en el caso de la OP, uno podría simplemente hacer:

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

ans = 

            A          B          C          D          E    
         _______    _______    _______    _______    ________

    A    0.81472    0.09754    0.15761    0.14189     0.65574
    B    0.90579     0.2785    0.97059    0.42176    0.035712
    C    0.12699    0.54688    0.95717    0.91574     0.84913
    D    0.91338    0.95751    0.48538    0.79221     0.93399
    E    0.63236    0.96489    0.80028    0.95949     0.67874

Aquí es una rápida y sucia de enfoque:

horzcat({'';'ROW1';'ROW2';'ROW3';'ROW4';'ROW5'}, ...
        vertcat({'FOO','BAR','BAZ','BUZZ','FUZZ'},...
                num2cell(rand(5))))

rendimiento:

ans = 

    ''        'FOO'       'BAR'       'BAZ'       'BUZZ'      'FUZZ'  
    'ROW1'    [0.3015]    [0.6665]    [0.0326]    [0.3689]    [0.6448]
    'ROW2'    [0.7011]    [0.1781]    [0.5612]    [0.4607]    [0.3763]
    'ROW3'    [0.6663]    [0.1280]    [0.8819]    [0.9816]    [0.1909]
    'ROW4'    [0.5391]    [0.9991]    [0.6692]    [0.1564]    [0.4283]
    'ROW5'    [0.6981]    [0.1711]    [0.1904]    [0.8555]    [0.4820]

Mateo Oberhardt, útil código, he añadido el nombre de la matriz, aquí está el nuevo código tan simple acaba de agregar una variable más
Y también dejo un ejemplo para usar, observe que p es una matriz de mxn.

—————CÓDIGO—————

function out = dispmat(M,name,row_labels,col_labels);
%% Matthew Oberhardt 
% 02/08/2013
% 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
cols = strrep(col_labels, ' ', '_');
rows = strrep(row_labels, ' ', '_');
%% create labels, space delimited
c_out = [];
for n = 1:length(cols)
c_out = [c_out,cols{n},' '];
end
c_out = c_out(1:end-1);
r_out = [];
for n = 1:length(rows)
r_out = [r_out,rows{n},' '];
end
r_out = r_out(1:end-1);
%% print
printmat(M,name,r_out,c_out)
end

———-EJEMPLO de matriz conv(5,4)————–

[m n] = size(conv);
for i=1:n
col{i} = ['K = ' num2str(i)];
end
for i=1:m
row{i} = ['n =' num2str(i)];
end
outMat(conv,'Convergence',row',col);

————–RESULTADO————————–

Convergence = 
K_=_1        K_=_2        K_=_3        K_=_4        K_=_5
n_=1      0.74218      0.42070      0.11101 9.86259e-006 9.86259e-006

He escrito algún código que pueda ser de ayuda — usa el ‘printmat función, pero los cambios de las entradas por lo que son células de vectores que contenga la columna &/o etiquetas de fila. espero que sea útil.

function out = dispmat(M,row_labels,col_labels);

% row_labels = '';
%% check that the row & col labels are the right sizes

end
if isempty(col_labels)
col_labels = cell(1,ncols);

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