I would like to sort matrix3, so that every column in output matrix is
sorted. Also I have to "unsort" it later on.

matrix1<-matrix(rnorm(100,354,78),ncol=10)
matrix2<-matrix(rnorm(100,225,102),ncol=10)
matrix3<-cbind(matrix1,matrix2)
nrCol<-length(matrix3[1,])
class1<-1:10
  for(i in 1:nrCol)
  {
    sorted.matrix<-matrix3[order(matrix3[class1,i]),]
  }
 for(i in 1:liczbaKolumn)
  {
   output<-sorted.matrix[order(matrix3[class1,i]),]
  }
