Y=filter2(h,x,’shape’) h为滤波器，x为要滤波的数据，将h放在x上移动进行模板滤波。shape可取 full, same, valid (不写默认是same)。本篇文章采用滑动平均fspecial(‘average’)创建一个均值滤波器，举例说明filter2的用法。
Let the microcontroller (such as STM32 MCU) compiler automatically embed the CRC32 value for firmware integrity check in bootloader. 通过在FLASH存储空间的最末尾设置两个int32大小的crc32Value和crc32Value2来实现嵌入式程序Bootloader自检。检查过程可以统一为，检查crc32Value的值是否正确，若不正确，检查crc32Value2的值是否正确。若都不正确，则程序错误，进行bootloader错误处理阶段。
For the three-phase PWM inverter, there are three commonly used coefficients to indicate the DC voltage utilization level, i.e. Modulation Level (调制度) M = \cfrac{V_R}{V_T} where V_R is the magnitude (note, not fundamental amplitude) of modulation wave, V_T is the Read more…
