In many physical systems what is observed is only data in the form of points on a set S . The nature of the dynamical system producing the data is unknown. From the distribution of data points one can construct a probability density function on S . The inverse problem for the Frobenius-...
If the initial time is t = 0, then the following initial values that satisfy the boundary conditions: atan(cos(pi/2*x)) for u(0) and 3*sin(pi*x).*exp(sin(pi/2*y)) for ∂u/∂t, The inverse tangent function and exponential function introduce more modes into the solution....
For analytic solutions, use solve, and for numerical solutions, use vpasolve. For solving linear equations, use linsolve. These solver functions have the flexibility to handle complicated problems. See Choose an Approach for Solving Equations Using solve Function. Solve differential equations by using ...
For example, ( For example, (33.1) is a .1) is a first first--order order equation equation which may be written as which may be written as yy'' =y =y. . The differential equation The differential equation yy'' ==xx^3 ^3 y y + + sin ( sin (x y x y'' '') is on...
We have removed 2nπ from the argument of the cosine for mathematical convenience (the transformation is exact): we wish that the modulation function varies slowly on the quantity nTR (we anticipate that θ will be very small). Next, in the spirit of the original Haus ME28, we introduce ...
An effective method for solving a partial differential equation of secondary hydrocarbon migration is put forward. 本文给出了一种高效率求解油气二次运移偏微分方程的方法. 来自期刊摘选 19. Multielement function calculus, infinite series , ordinary differential equation, partial derivatives, multiple integrals...
In addition to assuming master equation dynamics, we focus on the case where P represents some single-valued function \(f:{\cal{X}} \to {\cal{X}}\) over a finite space of “visible states” \({\cal{X}}\). For example, this would be the case for any physical system that ...

There are two main methods for solving the parabolic equation. • One is called the ‘split-step Fourier’ method [14]; the z-Fourier transform of the field is first computed and then the inverse Fourier transform. • The other is based on finite difference methods [18, 19]. In the...
