这种类型也是MATLAB独有的,类似于C语言中的指针(Pointer),但一个元胞(Cell)并不直接存内存的地址,而是指向某变量。 %%TheUltimateLegendofBigJohn 相当于段落文本 page{1}='You could find him on the field almost any day.';page{2}='Tall, dark hair, and eyes of steel gray.';page{3}='They say...
animal_data = struct; 接下来,为该结构体添加对应于我们感兴趣特性(物种数量和重量)的两个字段:species_count 和 weight_kg: matlab animal_data.species_count = []; animal_data.weight_kg = []; 现在我们已经成功定义了 animal_data 结构体及其两个字段。species_count 和 weight_kg 这两个字段都是空的...
There is no MATLAB function that examines every level of a structure of structures, or nested structure, to determine if a field exists. The 'isfield' function examines only the top level of a nested structure. To determine if a field exists at any other level,...

* Function xml_read first calls MATLAB's xmlread function and than converts its output ('Document Object Model' tree of Java objects) to tree of MATLAB struct's. The output is often in format of nested structs and cells. In the output data structure field names are based on XML tags....
