How can I create a LaTeX table from a MATLAB array?

I would like to create a LaTeX table from a MATLAB array.

If you have the Symbolic Math Toolbox, you can use the LATEX function in conjunction with SYM to create a LaTeX table to represent MATLAB data in a table format. For example:

A = [1 2 3; 4 5 6; 7 8 9];

latex_table = latex(sym(A))

The resulting value in latex_table will be:

 \left [\begin {array}{ccc} 1&2&3\\\noalign{\medskip}4&5&6\\\noalign{\medskip}7&8&9\end {array}\right ]

This string can then be pasted into any LaTex document.

Instead of vpa, you could also use sympref as it suggests in the latex() documentation.

sympref('FloatingPointOutput',true);

chr = latex(sym(pi))

This is a nice solution. Unfortunately it does not work well with doubles, as sym() will turn the doubles into fractions.

Frieder Wittmann, it does work:

%default with the sympref not set
>> latex(sym(rand))
ans =

    '\frac{4411405500742427}{9007199254740992}'

%set it
>> sympref('FloatingPointOutput',1)
ans =

  logical
   0

%and experiment again
>> latex(sym(rand))
ans =

    '0.4456'
