manually writing out matlab matrices in latex is really tedious. here’s how to save yourself the time:

assume you have some matrix L

>> s = sym(L);
>> v = vpa(s,5); # assign numerical precision
>> latex(v)

matlab should now spit out the latex source code that you can directly copy into your .tex file.

    Could you help me in inserting a matrix within a line…all my efforts are producing the matrix in the next line. Thanks in advance.

    Doesn’t work perfectly for me on 2010a.
    The output precision is the same.
    vpa(A,3) : I have 0.333
    but after latex(vpa(A,3))
    I have 0.33333333333333

    Try this:

    digits(4); //this changes the output precision
    s=sym(A,’d'); //the ‘d’ flag makes sure the sym output is in decimal form

    worked for me!

Did I get this wrong? Let me know!
