MATLAB: How to solve differential equation with MATLAB

differential equations

Hi,

I have a problem related to solving differential equation. The equation is:

(3/2)lnX + 3886/x = 19

I can not solve this equation. I must find 'x' value..

How can I solve this with Matlab?

Thanks for your help.

Hi Torsten,

Actually I have understood the first equation and x is nearly 372000 derived. But it is a very high value and I can say it is not logical for my solution.

When I try an arbitrary value as nearly 375, the solution can be acceptable for me. 375 may be more logical for me.

That is to say; can there be a second answer of this equation?

Best regards,

By the way: x=0 is a solution.

MATLAB: I have a multi variable equation (four variables). I want to write a piece of code that solves for any one variable given the other three, without changing the equation every time. Is that possible

syms A B C D
eqn=A-B*C^2*D^2==0;
solA=solve(eqn,A);
solB=solve(eqn,B);
solC=solve(eqn,C);
solD=solve(eqn,D);
