Internal function: row and column sums of matrices
Abbreviation for collapsing matrices
gsi.csum(x) gsi.rsum(x)
x |
the matrix |
gsi.csum computes the sums of all the columns of x and gsi.rsum computes the sums of the rows of x. For convenience, only finite values are added.
A numeric vector.
Do not use gsi.* functions directly since they are internal functions of the package

#A <- matrix(c(0,1,0,0,0,0),ncol=2) #b <- diag(3) #erg <- gsi.svdsolve(A,b) #erg #A %*% erg #diag(c(0,1,0)) # richtig
