Since the equation is in the generic form f (t, y, y ′) = 0, you can use the ode15i function to solve the implicit differential equation. Code Equation To code the equation in a form suitable for ode15i , you need to write a function with inputs for t , y , and y ′ that returns the residual value of the equation.

Posted Jul 8, 2010, I struggle with the same problem and I think it is quite fundamental to be able to solve such systems of equations. This is a "understood though not directly expressed" equation otherwise known as implicit equation. Solving such equation requires that you assume a value for f to start the iteration. The assumed values converge in few (less than 100) iterations. Please see belowfor how it convergence. Since the equation is in the generic form f (t, y, y ′) = 0, you can use the ode15i function to solve the implicit differential equation. Code Equation To code the equation in a form suitable for ode15i , you need to write a function with inputs for t , y , and y ′ that returns the residual value of the equation.

The fzero function seems to be appropriate here: g = 1.27; ar = 44.11; fcn = @ (M) (1./M)* ( (2/ (g+1)).* (1+ ( ( (g-1)/2)*M.^2)).^ ( (g+1)/ (2* (g-1)))) - ar; M = fzero (fcn, 1) In the vast majority of cases, the equation to be solved when using an implicit scheme is much more complicated than a quadratic equation, and no analytical solution exists. Then one uses root-finding algorithms, such as Newton's method, to find the numerical solution. You can rephrase your equation by defining like below f(y) and then find the root of it with fsolve. from scipy.optimize import fsolve def f(y,b=2,x=1,n=0.015,S_0=0.002,Q=21): return (1/n)*((y*(b+x*y))**(5/3))/((b+2*y*(1+x**2)**(1/2))**(2/3))*S_0-Q a=fsolve(f,1) print(a) print(f(a)) Any equation that can be written as y = f (x). Implicit equations like x^5y + y^2 - 1 = y^3 cannot.

In this case, switch to Graph mode. Examples Solve each system of implicit equations below. For example, the implicit equation of the unit circle is. An implicit function is a function that is defined implicitly by an implicit equation, by associating one of the variables (the value) with the others (the arguments). Thus, an implicit function for y in the context of the unit circle is defined implicitly by 1. Maple is powerful math software that makes it easy to work with implicit equations, and to analyze, explore, visualize, and solve mathematical problems from virtually every To differentiate an implicit function y(x), defined by an equation R(x, y) = 0, it is not generally possible to solve it explicitly for y and then differentiate.

In this case, the answer appears as the empty set, A contradiction equation is never true, no matter what the value of the variable is. In this case, the a (Try, for example, to solve the last equation for y .) The y s in such "mixed-up" equations are often called implicit functions of x . Using the word "function" here is  In other words, the equation is implicit in the friction factor f.
