Using Newton's Iterative method to find the root of the following equation near 1.5:2x^3-4x^2+3x-6=0 As for the Newton iterative method, in the course of computational methods, the basic formula is: xn+1=xn-f (Xn)/F *(Xn) xn+1 is the n+1 iteration result,Xn is the nth iteration result,f * ( Xn) is the Guide function value of f (Xn) . Basic steps: The first step is to rewrite the equation as polynomial f (x) =2x^3-4x^2+3x-6, given initial value X0; T

First, to discuss a simple example, if you want to find the point of the function f (x) =0, you can do the following.If our initial value is X0, then the tangent of f (x) at that point, looking for a tangent to the x-axis intersection, the point as a known point, looking for a tangent, repeat the above operation, you can quickly approximate f (x) =0 point.The idea is used to solve the maximum likelihood function, the general maximum value satisfies = 0, then the operation can be done. If it is a

This article describes how to use python to calculate Newton's iterative polynomials. it involves the related skills of Python mathematical operations. For more information, see the example in this article. Share it with you for your reference. The

1 Gradient Descent methodWe use the gradient descent method to find the x corresponding to the minimum value f (x) of the objective function, so how do we find the minimum point x? Note that our X is not necessarily one-dimensional, it can be

Today, it is found that the terminating condition of the iterative process was incorrectly written, and should be terminated when the gradient value is less than a certain value, instead of the gradient value +hessian* increment less than a certain

This is a very interesting little animation, very simple. Follow me step-by-step. 1, create a shelf, such as figure. 2, create a nurbs ball and move it. 3, in the side view using the X key to create two EP curves. 4, create a circle, in the side

Mathematical principle derivation: f (x) = x2-n---formula (1) n is a value that requires a square root, such as the square root n = 100, which requires 100, so the problem is converted to the 0 point of F (x), the derivative of f (Xn) is the slope

nothing to do with particle fluctuations, but has aroused heated debate on the color attributes. In the eyes of gleemadi, the difference in color is caused by the different frequencies of light waves. His experiment attracted interest from Robert Hoke. Hooku was originally a lab assistant to poyier, a member of the Royal Society of England, and also a lab administrator. He repeat greemadi's work and carefully observes the colors mapped by light in the soap bubble and the radiance of light over
