Thestruct2cellfunction does not return field names. To return the field names in a cell array, use thefieldnamesfunction. example Examples collapse all Create a structure. S.x = linspace(0,2*pi); S.y = sin(S.x);
Create a structure. Get S.x = linspace(0,2*pi); S.y = sin(S.x); S.title = 'y = sin(x)' S = struct with fields: x: [0 0.0635 0.1269 0.1904 0.2539 0.3173 0.3808 0.4443 0.5077 0.5712 0.6347 0.6981 0.7616 0.8251 0.8885 0.9520 1.0155 1.0789 1.1424 1.2059 1.2693 1.3328 1.3963 1.459...
To index into a structure array, use array indexing. For example,patient(2)returns the second structure. patient(2) ans =struct with fields:name: 'Ann Lane' billing: 28.5000 test: [3×3 double] To access a field, use array indexing and dot notation. For example, return the value of ...

I have a structure s(1).x = 5; s(2).x = 6; s(1).y = 1; s(2).y = 8; how can i convert this into an array of x values and an array of y values, preferably without using a for loop? Im trying to plot(s(:).x, s(:).y) but it only plots one point hence why ...
Use [] to specify the value of the empty field. Get s = struct('f1','a','f2',[]) s = struct with fields: f1: 'a' f2: [] Fields with Cell Arrays Copy Code Copy Command Create a structure with a field that contains a cell array. Get field = 'mycell'; value = {...

In Matlab we have two ways to create a structure array, one is directly with the assignment statement to create, the second is to use the function struct () function to create. 直接用赋值语句创建,代码如下如所示: Directly with the assignment statement to create, the code is shown below: ...
This MATLAB function creates a structure array from the information contained in the cell array and using the specified field names.
