如何测试表中的列是否存在?例如isfield(T,'Hold')返回0.Exist,isstruct也不行.我需要测试才能简单地返回真或假的结果.
请参阅:表格属性
例如:
LastName = {'Smith';'Johnson';'Williams';'Jones';'Brown'};
Age = [38;43;38;40;49];
Height = [71;69;64;67;64];
Weight = [176;163;131;133;119];
BloodPressure = [124 93; 109 77; 125 83; 117 75; 122 80];
T = table(Age,Height,Weight,BloodPressure,...
'RowNames',LastName);
myquery = 'Age';
columnexists = ismember(myquery, T.Properties.VariableNames)
