### 6.7. Specialized Two-Dimensional Plots

Besides drawing plots using plot command, there are many specialized graphics functions in MATLAB for 2-D plotting. Some of the specialized 2-D plot functions are discussed in the following section.

#### 6.7.1. Logarithmic Plot Function

These are further classified as

1. semilogx: It plots with logarithmically spaced x-axis.

2. semilogy: It plots with logarithmically spaced y-axis.

3. loglog: It plots with both the axes logarithmically spaced.

##### 6.7.1.1. semilogx

In semilogx command, the x-axis is drawn on logarithmic scale and y-axis on linear scale. The syntax is

semilogx(x,y)

where

x is the vector of x-variables, and

y is the vector of y-variables.

##### Example 6.14.
 Plot function x= e-a, y = a2 where 0<=a<=10, using
