patient =struct with fields:name: 'John Doe' billing: 512 test: [3x3 double] With dot notation, you also can access the value of any field. For example, make a bar chart of the values inpatient.test. Add a title with the text inpatient.name. If a field stores an array, then this...
How can you take a cell array array of fieldnames and a cell array of values, and convert them into a structure without looping? names = {'f1','f2'}; values = {1 2}; structure = struct(???) 댓글 수: 0 댓글을 달려면 로그인...
a是个1×3的结构数组，分别存储的数据名是x1,x2,x3；x1，x2，x3是数、数组、矩阵乃至结构数组都是可以的。类比：书桌有3个抽屉，抽屉1放x1，抽屉2放x2，抽屉3放x3，x1，x2，x3都可以是空的也可以是1件东西，也可以是很多东西
Cell array is a unique data type in MATLAB. It is a kind of array. Its internal elements can belong to different data types. In terms of conceptual understanding, it can be regarded as very similar to the structure in the C language and the objects in C++. similar. Cell array is a ...
