Y=20*log10(abs(H))abs(H))是取H的绝对值 然后这是一个计算式子，y等于20乘以log以10为底的abs(H).你这是什么语言？matlab？

一、abs()函数——获取绝对值功能:返回数字的绝对值 语法:abs(x) 例子:循环输出列表中定义的数字的绝对值tupleabs = [12.45,0,-19.69] for i in tupleabs: print(abs(i)) 输出结果: 12.45 0 19.692.定义函数,用于输出2个数字相乘后的绝对值def aabs(value1,value2): return abs(v ...
If we calculate 100we get 1. This matches the number in cell B25. To calculate 10 to the power of 0 (zero) in Excel we can use the caret character ^, here is how: =10^0 This will calculate 10 to the power of 0 (zero) in an Excel formula. We can also use thePOWER function:...
