Displaying Tabular Data with heading in matlab

Dear All, I intend to display result of my calculation in a way that each column will have a heading in the command window. I want x values neatly displayed under x-val; y values under y-val etc; thanks if you can help. Here is my code:

x =1:20;
y= x.^2;
z = x*20;
table =[x; y; z];
disp('Table shows table values')
disp('x-val, y-val, z-val')
fprintf('%8.2f %10.1f %12.2f\n', table)

Try this:

fprintf('   x-val,     y-val,       z-val\n')
fprintf('--------------------------------\n')
fprintf('%8.2f %10.1f %12.2f\n', table)

Chuzymatics - depending upon your version of MATLAB (I think from R2013b and above) why not try and use the table function? Something like the following may work

 T = table(x',y',z','VariableNames',{'xval','yval','zval'})

which creates a table as

 T = 

    xval    yval    zval
    ____    ____    ____

     1        1      20 
     2        4      40 
     3        9      60 
     4       16      80 
     5       25     100 
     6       36     120 
     7       49     140 
     8       64     160 
     9       81     180 
    10      100     200 
    11      121     220 
    12      144     240 
    13      169     260 
    14      196     280 
    15      225     300 
    16      256     320 
    17      289     340 
    18      324     360 
    19      361     380 
    20      400     400

Note that the inputs to table are columns (that is why there is a transpose for each input variable) and the names of each variable (or columns names) is specified in the array of strings (note that these names must be valid MATLAB variable names, that is why I removed the dash from each).

Try the above and see what happens!

Many thanks. My version of MATLAB is 2007 so the table function is not there. However, I edited and ran my code and got the error:

??? Error using ==> subsindex
Function 'subsindex' is not defined for values of class 'cell'.

Error in ==> fmattOpt at 9

 T = table(x',y',z','VariableNames',{'xval','yval','zval'})

Why does your code include Geoff's table() function which you admit you don't have since you have an antique version of MATLAB? You can't use table like that. Your table is a simple numerical matrix.
