matlab % 假设s是一个结构体,包含字段x和y s.x = 1.1; s.y = 2.2; % 创建一个双精度数组 doubleArray = [s.x, s.y]; 使用struct2array函数: struct2array函数可以将结构体转换为数组,但默认情况下,它返回的是一个元胞数组(cell array)。你可以进一步处理这个元胞数组,将其转换为双精度数组。 mat...
MATLAB struct 结构数组 方法/步骤 1 第一,通过“.”创建结构数组。在命令行窗口输入如下代码:student.name='Jason'; student.class='class 3';student.results={'English','Maths';85,95};student.system=[1,2,3;4,5,6;7,8,9];然后输入student,按回车查看...
field1 = 'f1'; value1 = zeros(1,10); field2 = 'f2'; value2 = {'a', 'b'}; field3 = 'f3'; value3 = {pi, pi.^2}; field4 = 'f4'; value4 = {'fourth'}; s = struct(field1,value1,field2,value2,field3,value3,field4,value4) s=1×2 struct array with fields: f1 ...
Convert Nonscalar Structure Array to Table Create a nonscalar structure array, S. S(1,1).Name = "Chang"; S(1,1).Smoker = "Y"; S(1,1).SystolicBP = 124; S(1,1).DiastolicBP = 93; S(2,1).Name = "Brown"; S(2,1).Smoker = "N"; S(2,1).SystolicBP = 122; S(2,1...
case2:具有一个字段的结构体 创建包含一个字段的非标量结构体。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 field='f';value={'some text';[10,20,30];magic(5)};s=struct(field,value)s=3×1struct arraywithfields:f 查看每个元素的内容。
1x2 struct array with fields: type color x 得到维数为1×2的结构数组s,包含了type、color和x共3个字段。这是因为在struct函数中{'big','little'}、{'blue','red'}和{3,4}都是1×2的元胞数组,可以看到两个数据成分分别为: s(1,1)
A = arrayfun(@(x) mean(x.f1),S,'UniformOutput',false) A = 1x3 cell array {1x5 double} {1x10 double} {1x2 double} 代码语言:javascript 代码运行次数:0 运行 AI代码解释 *[B1,...,Bm]=arrayfun(___)*当 func 返回 m 个输出值时,[B1,...,Bm]=arrayfun(___)返回多个输出数组B1,.....
Convert table to structure array collapse all in pageSyntax S = table2struct(T) S = table2struct(T,"ToScalar",true)Description S = table2struct(T) converts the table or timetable, T, to a structure array, S. Each variable in T becomes a field in S. If T is an m-by-n table...
1x2 struct array with fields: type color x 得到维数为1×2的结构数组s,包含了type、color和x共3个字段。这是因为在struct函数中{'big','little'}、{'blue','red'}和{3,4}都是1×2的元胞数组,可以看到两个数据成分分别为: s(1,1)
If value is not a cell array, or if value is a scalar cell array, then s is a scalar structure. For instance, s = struct('a',[1 2 3]) creates a 1-by-1 structure, where s.a = [1 2 3]. If value is a nonscalar cell array, then s is a structure array with the same ...
