MATLAB: How to use matlab to find the solution of an equation when equal to zero using variables without substituting with numbers

equalityequation

I want to find how can I use matlab to find the solution of an equation when equal to zero using variables without substituting with numbers?

for example if the equation is : (x^2) – (y^2) = 0

the answer will be (x=y)

That is what the 'solve' function of the Symbolic Toolbox endeavors to do. It is not always successful, but it capable of some remarkable results.

MATLAB: I failed to solve 4 equation differential equation. I’m giving the code. the same code for two equation worked well. The point the program stuck is dsolve(ode1,ode2,ode3,ode4) or dsolve(odes) and never it finishes.

Your equations ode1 and ode4 actually contains linearly dependent terms which are

3*u + 4*v(ode1), 6*u + 8*v(ode4)

This situation brings about infinitely many solutions to your system, therefore actually a unique solution can not be found. For instance if you change your term into

6*u + 7*y

in ode4, you will see that a unique solution is quickly found.
