To evaluate & plot Bessel function of 1st kind using scilab

To evaluate & plot Bessel function in scilab:

AIM OF THE EXPERIMENT:

To evaluate & plot Bessel function of 1st kind using scilab.

REQUISITES:

A PC/laptop.

Scilab 6.0.0 must be installed.

THEORY:

The linear second order ordinary differential equation of type

$$x^2{y}^{\prime \prime }+x{y}^{\prime }+\left(x^2-v^2\right)y=0$$

is called the Bessel equation. The number $v$ is called the order of the Bessel equation.

Scilab is loaded with varieties of function to handle Bessel functions & modified Bessel function of its 1st & 2nd kind. Here Bessel function of 1st kind is plotted.

PROCEDURE:
1. Switch on your PC/laptop.

2. Go to all programs & open scilab 6.0.0.

3. Go to Scinotes.

4. Write the coding/program.

5. Save the file & use extension name .sci

6. Then execute & go to the scilab console window for output.
7. Go to scilab graphic window to write the graph.

CODING:   

clf()
x = linspace(0,40,5000)';
plot2d(x,besselj(0:4,x), style=2:6, leg="J0@J1@J2@J3@J4")
legend('I'+string(0:4),1);
xtitle("Some Bessel functions of the first kind")
