MATLAB Lesson 10 - Log scale plots When dealing with very large values or very small positive values, it is useful to plot data or functions using a log scale. A log scale can be used either on the x-axis, or the y-axis or both. Introduction to Log Plot Matlab Log Plots are the two-dimensional graphs that have a logarithmic scale in both horizontal and vertical axes. Logarithms can be written as the inverse of an exponential equation. The most common base of any logarithmic equation is always considered to be 10 if it is not specified. semilogx (X,Y) plots x - and y -coordinates using a base-10 logarithmic scale on the x -axis and a linear scale on the y -axis. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length.
Learn more about log, log10 newfts = log10(tsobj) calculates the common logarithm (base 10) of all the data in the data series of the financial time series object tsobj and returns the result in the object newfts. log10(x) returns the logarithm to the base 10 of x. If x is an array 다음 MATLAB 명령에 해당하는 링크를 클릭했습니다. Something strange seems to be happening in Matlab and i dont understand why if im calculating a matrix called M, using actual numbers lets call them A,B and reading from another matrix say M2; M = 5*log10(A) - B + M2; I am trying to plot a best fit line on a probability density function with logarithmic axes. The Y-axis (PDF) is 10^-12 to 10^-28, while the X-axis is 10^10 to 10^20. C/C++ 코드 생성 MATLAB® Coder™를 사용하여 C 코드나 C++ 코드를 생성할 수 있습니다.

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. LOG vs LOG10 plot . Learn more about loglog, log10, log A Problem with log10.
