取数组a中第2行到第5行，第6列到第8列的数据。
相当于从a中取出一个4*3的矩阵。
你自己用一个例子就能理解了：
a=rand(7,9)a(2:5,6:8)结果：
a=0.69910.84070.25110.91720.05400.01190.60200.22900.44270.89090.25430.61600.28580.53080.33710.26300.91330.10670.95930.81430.47330.75720.77920.16220.65410.15240.96190.54720.24350.35170.75370.93400.79430.68920.82580.00460.13860.92930.83080.38040.12990.31120.74820.53830.77490.14930.35000.58530.56780.56880.52850.45050.99610.81730.25750.19660.54970.07590.46940.16560.08380.07820.8687ans=0.33710.26300.91330.16220.65410.15240.79430.68920.82580.31120.74820.5383
