Standard finite difference method
Webb1 juli 2005 · It can be seen that standard errors for estimates obtained by using the three different methods are also similar. The standard errors of the estimates are largest for λ of about 5 and diminish for larger λ , with the method based on the total number of non-infectious aliquots giving the largest standard errors and the likelihood-based method … WebbIn order to save materials and reduce the weight of the structure, the section size of the beam will vary with the length of the beam. Therefore, in the steel frame structure, in addition to the standard form of joint area, there are also different beam heights on both sides of the column in the form of special joint area.

The finite difference method relies on discretizing a function on a grid. To use a finite difference method to approximate the solution to a problem, one must first discretize the problem's domain. This is usually done by dividing the domain into a uniform grid (see image to the right).
