Numerical Integration
From KratosWiki
Numerical integration refers to all the procedures, algorithms and techniques in the numerical analysis to obtain an approximate solution to a definite integral.
That is, how to obtain a numerical value of:
- Failed to parse (PNG conversion failed; check for correct installation of latex and dvipng (or dvips + gs + convert)): \int_\lambda_a^\lambda_b\! f(\lambda)\, d\lambda.
For our interest in the Finite Element Method, the purpose is to describe how the element matrices can be integrated numerically.
