example. 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, … Compute the log base 10 of symbolic input. The result is in terms of log. syms x f = x^2; fLog10 = log10 (f) fLog10 = log (x^2)/log (10) Convert symbolic output to double by substituting for x with a number using subs, and then using double. Use your actual data as labels, but scale the plotted data with log10.

There are two ways to make a log-log plot in MATLAB. The first is to use the plot command to plot log (y) vs. log (x) on a linear scale. plot (log10 (x), log10 (y)) Alternatively, you can use the loglog command to make a plot with log-scale axes: There are two types of log plots in MATLAB: Log-log plot; Semi log plot; Log-Log Plot. When we use a logarithmic plot with both axes in log scale, i.e. x-axis and y-axis both are represented in log scale, it is called log-log plot. For example: Fig. 2.
此 MATLAB 函数 在 x 轴和 y 轴上应用以 10 为底的对数刻度来绘制 x 和 y 坐标。 要绘制由线段连接的一组坐标，请将 X 和 Y 指定为相同长度的向量。

1 Governing 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。 If only the ordinate or abscissa is scaled logarithmically, the plot is referred to as a semi-logarithmic plot. Logarithmic units [ edit ] A logarithmic unit is a unit that can be used to express a quantity ( physical or mathematical) on a logarithmic scale, that is, as being proportional to the value of a logarithm function applied to the ratio of the quantity and a reference quantity of the I am trying to plot a matlab semilogx plot. How can I define a logspace in matlab from 400 nm to 700 nm?
