Declaring a complex number in MATLAB. Complex numbers in MATLAB are doubles with a real part and an imaginary part. The imaginary part is declared by using the 'i' or 'j' character. For example, to declare a variable as '1 + i' just type: >> compnum = 1 + i compnum = + i >> compnum = 1 + j compnum = + i. Heat transfer is the area of engineering science which describes the energy transport between material bodies due to a difference in temperature. The three different modes of heat transport are conduction, convection and radiation. In most problems, these three modes exist simultaneously. However, the significance of these modes depends on the problems studied and often, .

A GUI is disclosed including a set of visualization routines designed to improve display, visualization and manipulation of multi-dimensional data. Many of the routines combine 2D and 3D renderings with domain selecting criteria and stacking criteria with line segments connecting variable values between records in a given dataset or between corresponding variable values Cited by:

In this book the two-dimensional barrier is removed. The author presents three new theorems which establish a link between all two-dimensional boundary element techniques, and also proves that any of these methods, with mild conditions, can be used to approximate three- and higher-dimensional problems of the LaPlace or Poisson type.

The Complex Variable Boundary Element Method (CVBEM) is an approximation method useful for solving problems involving the Laplace equation in two dimensions. It has been shown to be a useful modelling technique for solving two-dimensional problems involving the Laplace or Poisson equations on arbitrary domains.

The complex variable boundary element method (CVBEM) has been shown to be a mathematically sound approach for modeling two-dimensional potential problems.
The foundations of the CVBEM method rests in complex variable theory, Author: Anthony N. Johnson, T.V. Hromadka. The boundary element method (BEM) has been known for some time to be extremely useful for the solution of elastic stress analysis problems involving high stress/strain gradients.
In particular, the method has been extensively used for the study of both two and three-dimensional fracture mechanics problems. In this work, a conceptual numerical solution of the two-dimensional wave partial differential equation (PDE) is developed by coupling the Complex Variable Boundary Element Method (CVBEM) and a generalized Fourier series.
The technique described in this work is suitable for modeling initial-boundary value problems governed by the wave equation on a rectangular Author: Bryce D.
