i have data as follows as

      2               1     -0.307799        0.00
      3        0.544459     0.0153522        0.01

How can I get data like this in matlab and put it in table?

I calculated function and I want to put it in tables for various parameters.

Thanks

You can do that using a regular table but you cannot use ‘f(x)’ as a variable name because it is not a valid MATLAB variable name. I have changed it to ‘fx’ here:

Data = [  2               1     -0.307799        0.00
          3        0.544459     0.0153522        0.01
          4        0.566101    0.00070708        0.02
          5        0.567143  -1.40255e-08        0.03
          6        0.567143   1.50013e-12        0.04
          7        0.567143             0        0.05];

VarNames = {'count', 'x', 'fx', 'initial'};
T = table(Data(:,1),Data(:,2),Data(:,3),Data(:,4), 'VariableNames',VarNames)

thank you, i want equivalent code in R2013a to display results in command window and workspace,because your code introduced in R2013b.

[Star Strider]

To do it without the table functions, you would have to use a couple of fprintf statements to print it to the Command Window:

Data = [  2               1     -0.307799        0.00
          3        0.544459     0.0153522        0.01
          4        0.566101    0.00070708        0.02
          5        0.567143  -1.40255e-08        0.03
          6        0.567143   1.50013e-12        0.04
          7        0.567143             0        0.05];

VarNames = {'count', 'x', 'f(x)', 'initial'};

fprintf(1, '  %s\t\t%s\t\t\t%s\t\t%s\n', VarNames{:})
fprintf(1, '\t%d\t%06f\t%12.5E\t%.2f\n', Data')

    count    x      f(x)    initial
    2  1.000000  -3.07799E-01  0.00
    3  0.544459   1.53522E-02  0.01
    4  0.566101   7.07080E-04  0.02
    5  0.567143  -1.40255E-08  0.03
    6  0.567143   1.50013E-12  0.04
    7  0.567143   0.00000E+00  0.05

Note: The output looks correct in the Command Window. The ‘tab’ distances are different in the Answers windows.

thank you , but i need to show in workspace as matrix , i.e, add name row (( size 1xn ))for every column in number matrix (( size mxn )) as V=[ w n u ] (size 1x3) ; M=[ 1 2 3; 4 5 6;7 8 9; 10 11 12] size(4x3). M=

[Star Strider]

My pleasure.

You can only do that with a table object, and you can only do that with R2013b or later.

Another option is:

DataCell = {VarNames, Data};

That puts all the variables in a cell array, but does not actually create a table. That’s as good as it gets without the table funciton.

h={'count' 'x' 'f(x)' 'initial'}
data=[2               1     -0.307799        0.00

f=figure;
t=uitable(f,'data',data,'columnname',h)

Thank you, but how to display results in command window and workspace? because results display as figure!!
