MATLAB, like Maple and other mathematical software but in contrast to spreadsheets like Excel, automatically allows and works with complex numbers. All arithmetic with complex numbers works in the usual way. This is because MATLAB is used widely in both mathematics where i is most commonly used for the square root of -1 and electrical Engineering where j is more commonly used for the square root of There are a number of special functions for working with complex numbers. These include creating complex numbers from real and imaginary parts, finding the real or imaginary part, calculating the modulus and the argument of a complex number. These are the constant pi and the square root and exponential functions. Use the format command to display all digits.

The exponential distribution models wait times when the probability of waiting an additional period of time is independent of how long you have already waited. For example, the probability that a light bulb will burn out in its next minute of use is relatively independent of how many minutes it has already burned. Create a probability distribution object ExponentialDistribution by fitting a probability distribution to sample data fitdist or by specifying parameter values makedist. Then, use object functions to evaluate the distribution, generate random numbers, and so on. Work with the exponential distribution interactively by using the Distribution Fitter app. You can export an object from the app and use the object functions. Use distribution-specific functions expcdf , exppdf , expinv , explike , expstat , expfit , exprnd with specified distribution parameters. The distribution-specific functions can accept parameters of multiple exponential distributions. Use generic distribution functions cdf , icdf , pdf , random with a specified distribution name 'Exponential' and parameters. The likelihood function is the probability density function pdf viewed as a function of the parameters.

The results using fractional powers depend on the distribution of the eigenvalues of the matrix. For example, to square each element in a matrix you can use A. The sqrt function is a convenient way to calculate the square root of each element in a matrix. An alternate way to do this is A.

Exponential functions are fundamental in various scientific and engineering disciplines, representing phenomena characterized by rapid growth or decay. MATLAB, a versatile numerical computing environment, provides an array of tools for plotting and analyzing these functions. This article serves as a guide on how to plot an exponential function of any equation under observation in MATLAB, offering insights into different approaches and customization options. Whether you are exploring the behavior of a specific exponential model or comparing multiple functions, MATLAB empowers you to create informative and visually appealing plots. MATLAB, with its powerful plotting capabilities, offers a straightforward approach to visualize these functions using the plot function. The plot function is a fundamental tool for creating 2D plots. It takes two input vectors, x and y , and connects the points defined by these vectors with lines. For plotting exponential functions, we first define a range of x values using the linspace function.
