Implement the following integer methods:
a) Method celsius returns the Celsius equivalent of a Fahrenheit calculation
celsius = 5.0 / 9.0 * ( fahrenheit - 32 )
b) Method fahrenheit returns the Fahrenheit equivalent of a Celsius the calculation
fahrenheit = 9.0 / 5.0 * celsius + 32
c) Use the methods from parts (a) and (b) to write an application either to enter a Fahrenheit temperature and display the Celsius or to enter a Celsius temperature and display the Fahrenheit equivalent.
Coaxial feed structures are widely used in ultra-wide band antennas . This paper modeled the characteristic of the monopole antenna feeded by coaxial line by FDTD in the time-domiain,which showes that . Firstly, it introduced the theory of the arithmetic and the particularly realization in the calculation then it described the use in the time-domain finally it analysed several characteristics of the monopole antenna. The arithmetic used in the microstrip antenna is also a quick and economical way to design the antenna.
迭代自適應(yīng)Simpson，Lobatto積分
In almost every standard book on numerics quadrature algorithms like the adaptive Simpson or the adaptive Lobatto algorithm are presented in a recursive way. The benefit of the recursive programming is the compact and clear representation. However, recursive quadrature algorithms might be transformed into iterative quadrature algorithms without major modifications in the structure of the algorithm.
We present iterative adaptive quadrature algorithm (adaptiveSimpson and adaptiveLobatto), which preserves the compactness and the clarity of the recursive algorithms (e.g. quad, quadv, and quadl). Our iterative algorithm provides a parallel calculation of the integration function, which leads to tremendous gain in run-time, in general. Our results suggest a general iterative and not a recursive implementation of adaptive quadrature formulas, once the programming language permits parallel access to the integration function.

im2dat.m is used to convert images to data which can be plotted using the standard MATLAB functions. This is very handy if you have plots on hardcopy and you want to convert them into data that MATLAB can use. The scanned image can be analysed by this function and the output will allow you to perform any calculation/manipulations that MATLAB can perform, e.g. curve fitting.
Quaternions are hypercomplex numbers (that is generalizations of the complex numbers to higher dimensions than two). For an introduction, refer to the Wikipedia article on Quaternions.
Quaternion toolbox for Matlab® extends Matlab® to allow calculation with matrices of quaternions in almost the same way that one calculates with matrices of complex numbers. This is achieved by defining a private type to represent quaternion matrices and overloadings of many standard Matlab® functions. The toolbox supports real and complex quaternions (that is quaternions with four real or complex components).
observable distribution grid are investigated. A distribution
grid is observable if the state of the grid can be fully determined.
For the simulations, the modified 34-bus IEEE test feeder is used.
The measurements needed for the state estimation are generated
by the ladder iterative technique. Two methods for the state
estimation are analyzed: Weighted Least Squares and Extended
Kalman Filter. Both estimators try to find the most probable
state based on the available measurements. The result is that
the Kalman filter mostly needs less iterations and calculation
time. The disadvantage of the Kalman filter is that it needs some
foreknowlegde about the state.
solvin Parbolic forms of PDE explicitly.
The error is O( h2+k2) or O(2,2) , it doesn鈥檛 develop the explicit local truncation error because it is unconditionally unstable and should not be used in any calculation.
This program incorporates the FV method for solving the Navier-Stokes equations using 2D, Cartesian grids and the staggered arrangement of variables. Variables are stored as 2D arrays. SIMPLE method is used for pressure calculation. UDS and CDS are implemented for the discretization of convective terms, CDS is used for the diffusive terms. The boundary conditions are set for the lid-driven cavity flow. Only steady flows are considered.
This section describes the development and extension of a basic power flow program in Matlab. To the extent feasible, complex vector operations are used, even for the calculation of the Jacobian matrix .
