or() in categorical variable
显示 更早的评论
I don't know why the results of index1 and index2 are different.
The variable
financial_status=[1,2,3,4,5];
index1 = find(financial_status==or(1,2));
index2 = find(financial_status>=1&financial_status<=2);

Because

ans =
logical
1
>>
You're apparently looking for
>> ismember(financial_status,[1,2])
ans =
1×5 logical array
1 1 0 0 0

Rarely are the actual indices returned by find needed, but can be if this is one of those cases that simply using the logical addressing array isn't sufficient.

ismember(financial_status, 1:2)
At the moment I cannot think of any computer language that expresses a set membership test in terms of an equality test. Which computer language were you inspired by?
