常用到的标准数组:全0数组、全1数组、单位矩阵、随机矩阵、对角矩阵及元素为指定常数的数组等。 表2-16 标准数组生成函数(e_two_20.m) 低维数组的寻址和搜索 数组中包含多个元素,在对数组的单个元素或多个元素进行访问时,需要对数组进行寻址操作。 表2-17 数组寻址技术(e_two_21.m) sort函数进行排序: 一维...
16 w = sort(v); 17 if rem(n,2) == 1 18 m = w((n + 1)/2); 19 else 20 m = (w(n/2) + w(n/2 + 1))/2; 21 end 22 end 另外,还有嵌套函数(Nested Functions),顾名思义,它定义在别的函数内,如下例子(取自Matlab R2014帮助文档“Nested Functions”,文件“parent.m”): 1 fu...

The ability to use SORT with a structure array is not available in MATLAB. As a workaround you can modify the following code that sorts an array of structures based upon a numeric first field: %%Create dummy struct array a.n=1;
