Subscripted assignment dimension mismatch. What should i do?
显示 更早的评论
So basically I downloaded the data provided by my professor and somehow when I worked on creating 2 coloumn for x, it said "Subscripted assignment dimension mismatch" and i got stuck... Here are my steps,
>> Y(:,1)=mgtndvi(:,1)
Y =
0.0485
-0.1794
0.1378
0.0124
0.0723
0.1893
0.1344
0.1159
0.1765
0.1340
0.1504
0.1257
-0.0646
>> mgtndvi=dlmread('mgt-ndvi0082-2.txt')
mgtndvi =
0.0485 4.2091
-0.1794 5.2015
0.1378 3.4137
0.0124 4.3957
0.0723 3.0455
0.1893 2.3837
0.1344 3.0349
0.1159 3.0462
0.1765 2.9660
0.1340 3.5063
0.1504 2.5861
0.1257 3.7062
-0.0646 4.5121
>> X(:,1)=ones(12,1)
X =
1
1
1
1
1
1
1
1
1
1
1
1
>> X(:,2)=mgtndvi(:,2) Subscripted assignment dimension mismatch.
and if I changed X into Y, it works
>> Y(:,2)=mgtndvi(:,2)
Y =
0.0485 4.2091
-0.1794 5.2015
0.1378 3.4137
0.0124 4.3957
0.0723 3.0455
0.1893 2.3837
0.1344 3.0349
0.1159 3.0462
0.1765 2.9660
0.1340 3.5063
0.1504 2.5861
0.1257 3.7062
-0.0646 4.5121
I am not sure whats going on....

You have
X(:,1)=ones(12,1)
which creates X as having 12 rows. You then try to
X(:,2)=mgtndvi(:,2)
but mgtndvi has 13 rows, not 12.
