X 가 구간 (0, Inf )에 있는 실수 값이면 log10 은 구간 ( -Inf, Inf )의 실수 값을 반환하게 됩니다. X 가 복소수 값이나 음의 실수 값이면 log10 함수는 복소수 값을 반환하게 됩니다. Direct link to this answer. https://it.mathworks.com/matlabcentral/answers/38453-inverse-of-log10#answer_47907.

Learn more about log, speed MATLAB 此 MATLAB 函数 返回数组 X 中每个元素的常用对数。该函数同时接受实数和复数输入。对于 X 在区间 (0, Inf) 内的实数值，log10 返回区间 (-Inf ,Inf) 内的实数值。对于 X 的复数值和负实数值，log10 函数返回复数值。 loglog (Y) 表示 x、y坐标都是对数坐标系 semilogx (Y) 表. >>log 10 ( 10 ) ans = 1 log ( 10 )等于loge ( 10 ), Matlab 中log ()的默认值为loge ()。. 1、log 函数 ：求自然对数 2、用法说明 y = log (x) 函数 对数组x的元素逐个进行以e为底的对数运算。.

Learn more about loglog, log10, log . You are so right..I just had trouble after I recalled that log(x) in Matlab means ln(x) in Maths. MATLAB will take the most recent definition (as it did in your code) and treat it as a variable rather than a function. I renamed your ‘log10’ array ‘Log_10’ to be sure that you do not ‘overshadow’ the log10 function.

1、log 函数 ：求自然对数 2、用法说明 y = log (x) 函数 对数组x的元素逐个进行以e为底的对数运算。. y = a+b*i，有log (y) = log (abs (y))+i*atan2 (b,a) 3、举例说明 >> x = 10 x = 10 >> y = log (x) y = 2.3026 >> x = 1:1 This MATLAB function returns the common logarithm of each element in array X. Skip to content. log10. Common logarithm (base 10) collapse all in page. Syntax. 説明. Y = log10 (X) は、配列 X の各要素の常用対数を返します。.
