Log Scale Matlab

The semilogx function plots x coordinates on a log scale by setting the xscale property of the axes to log.

Log scale matlab. In this figure we can see that both axes are represented in log. X axis and y axis both are represented in log scale it is called log log plot. Y logspace a b generates a row vector y of 50 logarithmically spaced points between decades 10 a and 10 b the logspace function is especially useful for creating frequency vectors. However if the axes hold state is on before you call semilogx the property does not change and the x coordinates might display on a linear scale.

However if the axes hold state is on before you call loglog those properties do not change and the plot might display on a linear or semilog scale. The matlab m file used to create this plot is experr m. There are two types of log plots in matlab. Types of log plots in matlab.

Remember when you use log there is an infinite distance in log scale between y 1 and y 0 since it has to pass through y exp 1 y exp 2 y exp 3 and so on each of which needs to be allocated the same screen distance as between y exp 0 and y exp 1. The loglog function plots coordinates on a log scale by setting the xscale and yscale properties of the axes to log.

The function is the logarithmic equivalent of linspace and the operator. To create a plot with a linear scale on the x axis and a log base 10 scale on the x axis you can use the function semilogx. How to scale logarithmic in surface plot. Log scale on both axes.

When we use a logarithmic plot with both axes in log scale i e.
