Hi all,
I¡¦m working on the SVD analysis. When I run my script,

.
.
.
.
x=svdcov(t2d(t1d|:,time|:),p2d(p1d|:,time|:),nsvd,homlft,hetlft,homrgt,hetrgt)
.
.
.
.

I got the error :

SVD: Warning all Y values in column are missing or are constant

I have printed t2d and p2d, the values are not constant. So what does the warning mean and how to solve it?
