Software for calculating eigenvalues and eigenfunctions of an integral operator

In summary, eigenvalues are scalar values that represent characteristics of a linear transformation, while eigenfunctions are vectors that correspond to those eigenvalues. An integral operator is a mathematical operator that takes a function as its input and produces a new function as its output. Software uses numerical methods to calculate eigenvalues and eigenfunctions of an integral operator, which has applications in mathematics, physics, and engineering. While it is possible to solve these problems by hand, software can provide more efficient and accurate solutions for complex systems.

Hi

can someone direct me to a free software to calculate eigenvalues and normalized eigenfunctions of a linear integral operator. I am trying to solve a fredholm integral equation with degenerate kernel using it instead of linear equations

thanks

There are a few different free software programs available for calculating eigenvalues and normalized eigenfunctions of a linear integral operator. Some of the most popular ones include SciPy, Octave, and Matlab. Each one has its own advantages and disadvantages so it is important to research each option before making a decision. Additionally, you may be able to find tutorials or online courses that provide instruction on using these programs.
