U=Us{1};

R
Yr <- Y
Us <- list()
Us[[1]] <- Yr %*% C
U <- Us[[1]] 
Fxy <- Y-(U[[1]] %*% t(C))


What I have tried:

The U, C, and Y values in the two pieces of code are the same except for the number of digits left after the decimal point. In matlab, four digits are kept, and in R, the calculation is accurate. Y is a 246 2 matrix, C is a 2 1 vector, and U is a 246-row list with dimensions that can be multiplied. Why does it work in matlab and R? Different results

Since we have no idea what numbers are input and what results you see, it is difficult to make a useful comment.

I'd be surprised if they were the same. Implementations are protected; ideas aren't.

Have you tried to type "format long" in matlab? What you see in matlab and what is saved might be two different things
