How to use Excel to calculate the distribution of the number of students in each grade? Many articles are recommended to use the COUNTIF function, but every statistic a fraction of a function to write a, very troublesome. For example, to show the distribution of numbers within a c58:c62 within a c2:c56 of less than 60 points, 60 to 70, 70 to 80, 80 to 90, and 90 to 100, enter the following 5 formula: 1. Number of persons with less than 60 points in

The Linux system uses time to calculate when the command executesWhen testing a program or comparing different algorithms, the execution time is very important, and a good algorithm should be the shortest. All UNIX-like systems are included time命令 , using this command to count time consumption.

in C language, there is a library dedicated to the functions of system time, program timing, etc.namely Time.hThe function clock_t clock (void) in time.h can complete the timing function.This function returns the number of CPU clock ticks (clock ticks) from "Open this program process" to "call clock () function in program", called Wall Clock Time (Wal-clock) in MSDN. Where clock_t is the data type used to hold the time, in the Time.h file, we can find the definition of it:#ifndef _clock_t_define

When an electronic compass, such as a hmc5883l or MPU9250, AK8963 the azimuth, it is often found that the angular jitter of the measurement is severe. Even though it does not move, the angle changes in a small range. At this time, we need to use the gyroscope to compensate the azimuth angle and fusion, and obtain the stable data. This paper only discusses the azimuth of 2D space, which is the z-axis data of the electronic Compass X, y two-axis data fusion gyroscope.1. Electronic compass and gyro
