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.

Help Center Help Center. This topic shows how to compute matrix powers and exponentials using a variety of methods. For example:. 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. For other roots, you can use nthroot. For example, calculate A. The m in sqrtm distinguishes this function from sqrt A , which, like A. In addition to raising a matrix to a power, you also can raise a scalar to the power of a matrix. When you raise a scalar to the power of a matrix, MATLAB uses the eigenvalues and eigenvectors of the matrix to calculate the matrix power. The matrix exponential is a special case of raising a scalar to a matrix power. The expm function is a more convenient way to calculate matrix exponentials. The matrix exponential can be calculated in a number of ways.

Mean of the exponential distribution, specified as a positive scalar value or an array of positive scalar values. Accepted Answer: madhan ravi.

If you specify mu as a scalar, then exprnd expands it into a constant array with dimensions specified by sz1, If you specify both mu and sz1, Mean of the exponential distribution, specified as a positive scalar value or an array of positive scalar values. To generate random numbers from multiple distributions, specify mu using an array.

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.
