1. Tutorial Purpose
1. master the basic idea of compound trapezoid formula and compound Simpson formula.2. Calculate the integral using the compound trapezoid formula and the composite Simpson formula for programming.3. Familiar with Matlab software.
2. experiment content1. Use the compound trapezoid
course, if the default score is set for some or all resources, the scores set for each resource separately are used instead of the default scores.In addition to the resource scores, nodes also have scores. The node score can be set as follows:Note that the node score settings are placed under the constraints configuration item in the configuration item, and are

In this way, if any resource in the resource group has a problem, it will be considered that the resource group has a problem. if the score is lower than that of other nodes, the entire resource group will be switched.
In addition, for the values of INFINITY and-INFINITY, the main purpose is to control whether to s
In a variety of competitions, it is often possible to get rid of a maximum score and a minimum score to calculate the average points of the calculation method.

Figure 1 is the rating table for a Grand Prix.
In the "Final score" item, we can use the large function or the small function to calculate, as in J3, enter the following formula:
=average (LARGE (b3:i3,{2,3,4,5,6,7}))
That can get the right results.
Here, we introduce the internal mean function--trimmean et provides, making the formula simpler:

In the "Final score" item, we use the internal average value function provided by ET--trimmean to compute the formula: =trimmean (B3:I3,2/8)
Here's a look at the Trimmean function:
The function of the Trimmean function is to return the internal average of the dataset. function Trimmean First removes a percentage of data points from the head and tail of the array, and
