    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.

    Abstract-In this paper, simple autonomous chaotic circuits coupled by resistors are investigated. By carrying out computer calculations and circuit experiments, irregular self-switching phenomenon of three spatial patterns characterized by the phase states of quasi-synchronization of chaos can be observed from only four simple chaotic circuits. This is the same phenomenon as chaotic wandering of spatial patterns observed very often from systems with a large number of degrees of freedom. Namely, one of spatial-temporal chaos observed from systems of large size can be also generated in the proposed system consisting of only four chaotic circuits. A six subcircuits case and a coupled chaotic circuits networks are also studied, and such systems are confirmed to produce more complicated spatio-temporal phenomena.

  • 已知数据文件IN.dat中存有200个四位数

    已知数据文件IN.dat中存有200个四位数,并已调用读函数rData()把这些数存入数组a中,请编写函数spellNum(),其功能是:把个位数字和千位数字重新组成一个新的二位数(新二位数的十位数字是原四位数的个位数字,新二位数的个位数字是原四位数的千位数字),以及把百位数字和十位数字组成另一个新的二位数(新二位数的十位数字是原四位数的百位数字,新二位数的个位数字是原四位数的十位数字),如果新组成的两个二位数一个是奇数,另一个为偶数,并且两个二位数中至少有一个数能被17整除,同时两个新数的十位数字均不为0,则将满足此条件的四位数按从大到小的顺序存入数组b中,并要计算满足上述条件的四位数的个数count。最后main()函数调用写函数wData(),把结果count以及数组b中符合条件的四位数输出到OUT.dat文件中。
