Let us see an example for exponential in Matlab, the exponential signal is defined as x1of n1 is equal to alpha (a1) power n1 U of n1. And this is an exponential signal related to the given equation. Then we plot a signal using x1 and y1 variable and plot function, plot is an inbuilt function available on Matlab it is plots the data in y1 versus the corresponding values in x1, x-axis is x1 which is varying from -5 to 15 comma y-axis is a function of x1. Then we write an exponential equation using exp function, we take an exp in parenthesis x1 is divided by 4 and these exponential values are assigned to variable y1, the equation is y1 = e x1/4, the value of x1 is varied from -5 to 15 and according to that the different values are assign to y1 variable. Firstly we take a range of axis -5 to 15 with a difference of 0.5, this range we take in an x1 variable. In this example, we display the exponential signal also using a plot function. Let us see an example related to exponential in Matlab, for exponential we use a Matlab syntax as ‘exp’, exp in parenthesis we take that variable names or we directly take the equation for exponential. Let us discuss examples of Exponential in Matlab. Step 3: then we use a plot statement with appropriate syntax to plot the exponential graph to visualize the exponential data. Step 2: then we use exp to get exponential values of the variable. Step 1: we take variables and assign values. The steps for Exponential plotting of the data using exp and plot statement:. Here we discuss the Introduction to MATLAB Exponential and its different Examples as well as its input and output.The syntax for Exponential in Matlab is as shown below:įor Exponential plotting of the data, we use exp and plot statements. We can also plot the functions which we have computed using the ‘plot’ expression, which allows us to visually interpret our function. We can use exp(x) syntax in MATLAB to calculate the exponential of any function which is passed as an argument. So, in this article, we learned how to use the exponential function in MATLAB. Let’s assume the values to be in the range. A plot is visually more powerful than normal data when we want to analyze the behavior of our function. Let us now learn how can we plot an exponential function. Let’s take value ‘-2’ for our understanding. We can also calculate the exponential of a logarithmic function. Let us now take exponential of another positive number. Let’s first compute the exponential of unity (1). Now we will understand the above syntax with the help of various examples Types of Exponential Function in MATLABīelow are the types of the exponential function in Matlab: 1. It can also be used for complex elements of the form z = x + iy. Y = exp ( X) will return the exponential function ‘e’ raised to the power ‘x’ for every element in the array X. Now we have brushed our understanding of exponential function, let’s understand its use in MATLAB. Example of MATLAB Exponential Functionīelow are the examples of MATLAB Exponential: This is a feature of exponential functions, indicating how fast they grow or decay. In the exponential decay of the function, the function decreases to half every time we add to x. G(x) =1/2 raised to the power x, which is an example of exponential decay, the function decreases rapidly as x increases.įor f(x) in the previous example, the function doubles every time we add to x. Following is a simple example of the exponential function:Īs depicted in the above graph, the exponential function increases rapidly. Let’s take another function:
