Examples. collapse all This MATLAB function plots x- and y-coordinates using a base-10 logarithmic scale on the x-axis and a linear scale on the y-axis. 2005-09-06 A Problem with log10. Learn more about log10, matrix array MATLAB I want to plot a bar chart in Matlab with (1) log-scale for x-axis and (2)bars in same width. But with the code below, the width of the bars are different.

Y = log10 (X) returns the base 10 logarithm of the elements of X. example Y = log10 (X) returns the common logarithm of each element in array X. The function accepts both real and complex inputs. For real values of X in the interval (0, Inf), log10 returns real values in the interval (-Inf, Inf). loglog (X,Y) plots x - and y -coordinates using a base 10 logarithmic scale on the x -axis and the y -axis. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix.

how Compute the log10 of the image in matlab and what mean log10 of image? and image is graylevel. for example: a=imread('image.jpg'); im2bw(a,log10); i want know the log10 how to effect on image? Y = log(X) returns the natural logarithm ln(x) of each element in array X. The log function’s domain includes negative and complex numbers, which can lead to unexpected results if used unintentionally.

The log base 10 of x is the base 10 logarithm of x which can be written as log10(x) or lg(x). Enter a number below, and the Log10 Calculator will calculate the result instantly. 2. When plotting, why do we need to plot with 10*log10(pxx) instead of only using pxx? Even when I use either ways of plotting, I cant seem to emulate the yrange in the example plot (attached).
