3. isfield判断struct是否有指定子filed % 定义一个struct patient.name = 'John Doe'; patient.billing = 127.00; patient.test = [79 75 73; 180 178 177.5; 220 210 205]; % 检测该struct是否存在指定filed isfield(patient,'billing') ans = 1 4.isempty用于判断矩阵是否为空 例子 B = rand(2,2,...
if isempty(MyStruct(ii).FieldName) ind=[ind, ii]; end end Then ind contains all the indexes where the structure field is empty. For instance if you then want to remove them from the structure: ThemeCopy MyStruct_init=MyStruct; MyStruct(ind)=[]; Hope this helps! 1 Comment Domin...
