s = struct( ... 'c', 0, ... 'nested', nested_struct ... ); array_of_nested_struct = repmat(s, 4, 1); How can I easily access an array of all of the values of the field a ? For example, I'd like to compute the sum as 테마복사 % sum(...
When I try to access the value of a field in a structure array as shown below: s = struct('x',{}); val = getfield(s,'x'); I receive the following error message: ??? Too many outputs requested. Most likely cause is missing [] around ...
Matlab中cell、table和struct三种Array都可以存储不同类型的数据,以table最为灵活。用cell2table和table2cell可以使cell和table互相转换。 读取cell中的数据可以用{}或()。例如,读取cell类型A的第二个数据可以用A{2},也可以A(2),区别在于()获取的类型是cell数组 ,{}是实际类型。如果想删除cell某个数据,必须用...
