MATLAB: How to Nonlinear Equation

equationssolve

Dear all,

I have two non-linear equation with variable h and x:

 h^2*((4*x)/exp(x^2) - 1/2)+ (2*h*x)/(x^4 + 1)=0
 2*h*(4/exp(x^2) - (8*x^2)/exp(h^2))=0

Does anyone know how to solve them?

Thank you so much!

help fsolve

Best wishes

Torsten.

ezplot(' x + (x^3*((4*h)/exp(h^2) - 1/2))/3 + (x^2*h)/(h^4 + 1)-2=0')

If you have the Symbolic Toolbox:

>> g = @(x) exp(x^2-2)
g = 
    @(x)exp(x^2-2)
>> syms x
>> diff(g(x))
ans =
2*x*exp(x^2 - 2)
