如何在 Octave(或 matlab)中比较两个结构的相等性？
尝试使用 == 运算符会产生:
binary operator `==' not implemented for `scalar struct' by `scalar struct' operations
最佳答案
使用 isequal 或 isequalwithequalnans 函数。示例代码:
s1.field1 = [1 2 3];
s1.field2 = {2,3,4,{5,6}};
s2 = s1;
isequal(s1,s2) %Returns true (structures match)
s1.field3 = [1 2 nan];
s2.field3 = [1 2 nan];
isequal(s1, s2) %Returns false (NaN ~= NaN)
isequalwithequalnans(s1, s2) %Returns true (NaN == NaN)
s2.field2{end+1}=7;
isequal(s1,s2) %Returns false (different structures)
isequal(s1, 'Some string') %Returns false (different classes)
