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.

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.

Version History Introduced before Ra expand all Ra: Perform calculations directly on tables and timetables The exp function can calculate on all variables within a table or timetable without indexing to access those variables.

Exponential values, returned as a scalar, vector, matrix, multidimensional array, table, or timetable. For complex values of X , Y is complex.

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. Then, we calculate the corresponding y values using the exponential function exp x.

The object property mu stores the parameter estimate. To use random , create an ExponentialDistribution probability distribution object and pass the object as an input argument or specify the probability distribution name and its parameters. This function fully supports thread-based environments. The exponential distribution is the only continuous distribution with a constant hazard function. Search MathWorks.

Weibull Distribution — The Weibull distribution is a two-parameter continuous distribution that has parameters a scale and b shape. The data type of Y is the same as that of X. Output Arguments collapse all r — Exponential random numbers nonnegative scalar value array of nonnegative scalar values. Just try the below code by copying and pasting:. For complex values of X , Y is complex. For an example, see Exponentially Distributed Lifetimes. If mu is an array, then the specified dimensions sz must match the dimensions of mu. Statistical Analysis of Reliability Data. Consequently, when you model survival times, the probability that an item will survive an extra unit of time is independent of the current age of the item. The maximum likelihood estimates MLEs are the parameter estimates that maximize the likelihood function for fixed values of x.
