Hello,

While doing SVD in R I cam across the following line of code:

cx <- sweep(x,2,colMeans(x), "-")
sv <- svd(x)
names(sv)

“d” “u” “v”

What is the sweep function doing here?Also what do the names d,u & v signify in this SVD??

Refer to this link.
Then go the Statement of the theorem topic.There’s given d,u and v in svd along with definitions
