MATLAB provides four functions that generate basic matrices. Here are some examples: Z = zeros(2,4). Z = 0 0 0 0. The basic Symbolic Math Toolbox is a collection of more than MATLAB To differentiate the Bessel function of the first kind, besselj(nu,z), with. For example, a length 51 filter with a lowpass cutoff frequency ω0 of π rad/s The kaiserord function estimates the filter order, cutoff frequency.

Each row of J contains the values of one order of the function evaluated at the points in z. Calculate the unscaled J and scaled Js Bessel function of the first kind J 2 z for complex values of z. Compare the plots of the imaginary part of the scaled and unscaled functions. For large values of abs imag z , the unscaled function quickly overflows the limits of double precision and stops being computable.
The scaled function removes this dominant exponential behavior from the calculation, and thus has a larger range of computability compared to the unscaled function. Equation order, specified as a scalar, vector, matrix, or multidimensional array. Example: besselj 3, Data Types: single double. Functional domain, specified as a scalar, vector, matrix, or multidimensional array.
On the complex plane, the magnitude of besselj grows rapidly as the value of abs imag Z increases, so exponentially scaling the output is useful for large values of abs imag Z where the results otherwise quickly lose accuracy or overflow the limits of double precision.
Example: besselj 3,,1. You can calculate Bessel functions of the second kind using bessely. The Bessel functions are related to the Hankel functions, also called Bessel functions of the third kind:. The Hankel functions also form a fundamental set of solutions to Bessel's equation see besselh. This function fully supports tall arrays. For more information, see Tall Arrays. Strict single-precision calculations are not supported. In the generated code, single-precision inputs produce single-precision outputs.
However, variables inside the function might be double-precision. This function fully supports thread-based environments. The order nu must contain nonnegative, real, integer values. This function fully supports distributed arrays. Choose a web site to get translated content where available and see local events and offers. Based on your location, we recommend that you select:. Compute the Bessel functions of the first kind for these numbers. Because these numbers are floating point, you get floating-point results.
Compute the Bessel functions of the first kind for the numbers converted to symbolic form. For most symbolic exact numbers, besselj returns unresolved symbolic calls. For symbolic variables and expressions, besselj also returns unresolved symbolic calls. Solve this second-order differential equation.
The solutions are the Bessel functions of the first and the second kind. Verify that the Bessel function of the first kind is a valid solution of the Bessel differential equation. Plot the Bessel functions of the first kind for 0 , 1 , 2 , 3.
Input, specified as a number, vector, matrix, or array, or a symbolic number, variable, array, function, or expression. If nu is a vector or matrix, besselj returns the modified Bessel function of the first kind for each element of nu. At least one input argument must be a scalar or both arguments must be vectors or matrices of the same size.
If one input argument is a scalar and the other one is a vector or a matrix, besselj nu,z expands the scalar into a vector or matrix of the same size as the other argument with all elements equal to that scalar. Abramowitz and I. Stegun, eds. New York: Dover,

Basic accuracy check applied for Bessel function of the second kind — Y 0 x :. The problematic areas can be located using error scatter plot. Red lines show the expected limits of relative error for convenience, we added another interval to cover whole x axis :. The spikes of error clearly coincide with zeros of Bessel function 0. To test accuracy near zeros in more detail we use the following function:. The nextafter x function computes next floating-point value just after x [ 15 ] towards infinity.
We use it to generate test arguments in close neighborhood of given point. Accuracy of besselj 0,x near first zero of J 0 x :. Situation is the same — besselj 0,x computes J 0 x incorrectly near zeros. In fact, all routines in MATLAB for computing Bessel functions of integer order suffer from accuracy loss in vicinity of function zeros.
Error can be arbitrary high, even to the point when none of the digits are correct. Below we just show relative error plots with obvious peaks near function zeros — indication of accuracy loss detailed analysis for every function can be easily done using routine above :. Certainly this situation is absolutely unacceptable, and TMW should re-consider its library for computing Bessel functions.
More surprisingly, the issue is endemic for nearly all libraries for computing Bessel functions in double precision! Below we present error plots for some commonly used open source and commercial libraries. All of them except one suffer from the same accuracy loss near function zeros — error may become arbitrary high. Boost 1. Cephes 2. In fact, computed function values have no correct digits in close vicinity of zeros.
