error in using year()
显示 更早的评论
I typed exactly the same code as in the reference provided below:
Year = year('05-Aug-2003')
and I get
Year =
2002
2002
2002
2002
2002
2002
2002
2002
2002
2002
2002
Why is that? Thanks.

There must be a variable called "year" in the workspace. Try this:
year=2002*ones(120,1);
Year = year('05-Aug-2003')
It got your answer.
Try this
year=1:120;
Year=year('05-Aug-2003')
Year =
48 53 45 65 117 103 45 50 48 48 51
notice
>> double('05-Aug-2003')
ans =
48 53 45 65 117 103 45 50 48 48 51
It turned out it converted the string '05-Aug-2003' into double numbers and used the numbers to index the existing matrix "year". The size of "year" happens to be large enough so the "Index exceeds matrix dimensions" error didn't happen.
I don't like this behavior.

@Binzi Shu: that is correct. When you create a variable with the same name as an inbuilt function/variable, you cannot use the inbuilt one. For this reason avoid using length, size, cell, i, j, year, etc.
