    1) Write a function reverse(A) which takes a matrix A of arbitrary dimensions as input and returns a matrix B consisting of the columns of A in reverse order. Thus for example, if A = 1 2 3 then B = 3 2 1 4 5 6 6 5 4 7 8 9 9 8 7 Write a main program to call reverse(A) for the matrix A = magic(5). Print to the screen both A and reverse(A). 2) Write a program which accepts an input k from the keyboard, and which prints out the smallest fibonacci number that is at least as large as k. The program should also print out its position in the fibonacci sequence. Here is a sample of input and output: Enter k>0: 100 144 is the smallest fibonacci number greater than or equal to 100. It is the 12th fibonacci number.

    北京大学ACM比赛题目 Write a program to read four lines of upper case (i.e., all CAPITAL LETTERS) text input (no more than 72 characters per line) from the input file and print a vertical histogram that shows how many times each letter (but not blanks, digits, or punctuation) appears in the all-upper-case input. Format your output exactly as shown.

  • PlotSphereIntensity(azimuth, elevation) PlotSphereIntensity(azimuth, elevation, intensity) h = Plo

    PlotSphereIntensity(azimuth, elevation) PlotSphereIntensity(azimuth, elevation, intensity) h = PlotSphereIntensity(...) Plots the intensity (as color) of a number of points on a unit sphere. Input: azimuth (phi), in degrees elevation (theta), in degrees intensity (optional, if not provided, a green sphere is produced) All inputs must be vectors or matrices of the same size. Data does not have to be evenly spaced. When there aren t enough points to draw a smooth sphere, additional points (with color) are interpolated. Output: h - a handle to the patch object The axes are also plotted: positive x axis is red positive y axis is green positive z axis is blue

  • The neuro-fuzzy software for identification and data analysis has been implemented in the MATLAB lan

    The neuro-fuzzy software for identification and data analysis has been implemented in the MATLAB language ver. 4.2. The software trains a fuzzy architecture, inspired to Takagi-Sugeno approach, on the basis of a training set of N (single) output-(multi) input samples. The returned model has the form 1) if input1 is A11 and input 2 is A12 then output =f1(input1,input2) 2) if input1 is A21 and input 2 is A22 then output =f2(input1,input2) 看不懂,据高手说,非常有用。

    :介绍了一种基于数字信号处理器(DSP)的移相调频(Phase-Shifted and Frequency-Varied,PSFV)PWM控制 逆变电源,给出了主电路拓扑结构,分析了其控制原理并设计了其控制程序流程图。新颖的PSFV 控制能够实现输出 电压90%的调整率,输出电流波动小于单纯移相调功PWM方式,并在轻载时保持连续。功率开关器件零电压零电流 通断(Zero-Voltage-Zero-Current Switching,ZVZCS)软开关的实现,有利于进一步提高开关频率和降低开关损耗。采用 高性能的专用DSP 芯片TMS320F2812 实现了系统的数字控制,满足了系统控制的灵活性和实时性,减小了系统的 体积和生产成本。仿真分析和实验结果证明了此控制模式的可行性与合理性。
