Matlab向量的生成方法

1、Matlab向量的生成方法

（1）直接输入法

（2）冒号生成法

（3）线性等分法

2、直接输入法

>> a=[1,2,3,4;5,6,7,8;9,10,11,12]

a =

     1     2     3     4
     5     6     7     8
     9    10    11    12

3、冒号生成法

>> b=1:2:100

b =

  Columns 1 through 17

     1     3     5     7     9    11    13    15    17    19    21    23    25    27    29    31    33

  Columns 18 through 34

    35    37    39    41    43    45    47    49    51    53    55    57    59    61    63    65    67

  Columns 35 through 50

    69    71    73    75    77    79    81    83    85    87    89    91    93    95    97    99

>> c=100:-2:1

c =

  Columns 1 through 17

   100    98    96    94    92    90    88    86    84    82    80    78    76    74    72    70    68

  Columns 18 through 34

    66    64    62    60    58    56    54    52    50    48    46    44    42    40    38    36    34

  Columns 35 through 50

    32    30    28    26    24    22    20    18    16    14    12    10     8     6     4     2

4、线性等分法

>> d=linspace(1,100,20)

d =

  Columns 1 through 10

    1.0000    6.2105   11.4211   16.6316   21.8421   27.0526   32.2632   37.4737   42.6842   47.8947

  Columns 11 through 20

   53.1053   58.3158   63.5263   68.7368   73.9474   79.1579   84.3684   89.5789   94.7895  100.0000
