关于MATLAB 的m文件。其详细介绍了怎么样应用MATLAB的应用。大家可以互相学习下(On the MATLAB m-files. Its kind described in detail how the application of MATLAB applications. We can learn from each other under the)

初学matlab可以参考的一些源代码，可以参照学习(Beginner matlab reference source code)

Field Ⅱ超声成像代码，可以进行单个孔径成像和合成孔径成像、加权和不加权仿真。(The calculation of point spread functions is done by placing a point in front of the transducer and then sweeping the beam over the point. This gives the point spread function of the imaging system. Field II can make this calculation for a number of points simultaneously and thereby reveal the dynamic focusing properties of the imaging system. A point phantom has been made for this purpose. It consists of a number of point targets placed with a distance of 5 mm starting at 15 mm from the transducer surface)

MATLAB is one of several tools for working with mathematics. As an experienced programmer, I was skeptical at rst. Why should I learn another programming language when I could do the work in C/C++? The answer was simple: working with MATLAB is easier! Yes, there are some instances when one would want to use another language. A compiled program, such as one written in C++, will run faster than an interpreted MATLAB program (where each line is translated by the computer when the program is run). For hardware design, one might want to write a program in Verilog or VHDL, so that the program can be converted to a circuit.

Spread spectrum merupakan sistem dimana sinyal yang dikirimkan memiliki bandwidth yang jauh lebih lebar daripada bandwidth sinyal informasinya sendiri. Proses pelebaran bandwidth sinyal informasi ini dilakukan pada sisi pengirim dan disebut spreading. Sebaliknya, proses penyempitan kembali bandwidth sinyal informasi dilakukan di sisi penerima, dan disebut despreading. Pada gambar 1 berikut menunjukkan proses yang terjadi pada sistem spread spectrum.
