Why doesn’t livescript display the results in LATEX form?

When I was using 2017a the results of symbolic operations resulted in LATEX form but why does it not happening in 2018b? Is there any option to change the settings perhaps?

[Walter Roberson]

There is a latex() call that might help for any one expression ?

[madhan ravi]

Yes sir Walter, but the display of results isn't like equations for instance

[madhan ravi]

One possible workaround that I know/found is that if i hover over a specific equation , I am able to see the equation in mathematical form , but it isn't fancy as the result being displayed as mathematical expression :/

madhan ravi Can you share your symbolic expression which you are trying to visualize? Because in my end I can see equations in LaTeX form in the live script.

[madhan ravi]

Koley thank you for replying. I mean any symbolic expression just appears as is.

When I'm executing the following demo code in Live Editor (R2018b) in my end, it is showing formatted output.

syms m1 m2 e1 e2 r1 r2 r
[r1,r2] = solve(m1*r1 + m2*r2 == 0, r == r1 - r2, r1, r2)
d = e1*r1 + e2*r2;
simplify(d)
alpha = sym('alpha');
syms m c
m = m1*m2/(m1 + m2);
r2 = -alpha/(m*r^2);
J = simplify(subs(2/(3*c^3)*d^2, r, r2))
syms E L phi
a = alpha/(2*E)
eccentricity = sqrt(1-2*E*L^2/(m*alpha^2))

Are you getting this output?

[madhan ravi]

Ok let me try that and get back as soon as I have access to my PC.

[madhan ravi]

Koley I tried the code you suggested:

[Subhadeep Koley]

Can you please try that code again after setting the Default Text Interpreter to 'tex' or 'latex' ?

set(0,'DefaultTextInterpreter','latex');

[madhan ravi]

Still the same unfortunately.

[madhan ravi]

Koley is it a bug?

[Subhadeep Koley]

It seems not a bug as I am getting expected output in my end. It can be some issue with the installation.

I assume you played around with the sympref command. Please restore the inital value for typeset outputs with

sympref('TypesetOutput','default');

Please note that any sympref changes are persistent over sessions.

Now that's a perfect bullyseye, thank you very much Ralf.

@ Ralf Hillebrand +1 Nice solution!
