I am a starter with Matlab Symbolic toolbox. I have a matlab equation which is the output of the toolbox

z=x^2/(2*r) + x^4/(8*r^3) + x^6/(16*r^5) + y^2/(2*R) + y^4/(8*R^3) + y^6/(16*R^5)

I want to convert this into a regular typographical symbolic form. I tried putting this in live editor and just running. This gives me a nice formatted symbolic equation, but the z is in normal matlab form and the rest in symbol form is on the next line.

z =

How do I make this into one line, all in symbol form. I just want to extract this equation and paste it into a report / paper.

Many thanks.

在 MATLAB Online 中打开

syms x y z r R

eqn = z == x^2/(2*r) + x^4/(8*r^3) + x^6/(16*r^5) + y^2/(2*R) + y^4/(8*R^3) + y^6/(16*R^5)

eqn =

Thanks. I want to put the equation into a google doc, so I outputted in latex form, and then copy into the MathType addon in gdocs, and its translates automatically. Seems to work.
