When you choose "log" as the scale for an axis, Matlab either chooses to use log10(x) or -log10(-x) as the transform, depending on whether your data is in the positive or negative domain. As you've found, you can't have both at the same time because both halves map data into the [-inf inf] space.

The function accepts both real and complex inputs. For real values of X in the interval (0 Common (base 10) logarithm. Syntax. Y = log10(X). Description.
log10(x) returns the Compute the log base 10 of symbolic input. Y = log10(X) Description. The log10 function operates element-by-element on arrays. Its domain includes complex numbers, which may lead to unexpected results if used unintentionally. Y = log10(X) returns the base 10 logarithm of the elements of X. Examples. log10(realmax) is 308.2547 and. log10(eps) is-15.6536 See Also.

Mapping Function: log10 ( x ). Compute the base-10 logarithm of each element of x . The Common Logarithm However, some computer software, such as Matlab, use log to denote the Both Matlab and Excel use log10(x) to denote log10. This page is about MATLAB Log10,contains matlab画y=lgx 为什么不对呢？ x= logspace(0,10); y=log(x); loglog(x ,How MATLAB log10 gives base 10 logarithm In this MATLAB exercise, you will learn how to plot data and how to fit lines to your data. that the line will depict a relationship between t and log10 L. In MATLAB, a line of slope 2.9537 and y-intercept −1.0636 appears to fit t range by taking the logarithm of the ratio.
