how to return multipy matrix in a function
Hello
I have a 100*100 matrix which is from a intensive computation, e.g. mat. Is there any method/function that return the max of every row and the subscript of maximum value simultaneously
#define the function
> returnfunction<-function(x){
+ value<-apply(x,1,max)
+ index<-apply(x,1,which.max)
+ }
> mat<-matrix(c(3,5,7,2,1,10,4,3,2),3)#initilize the matrix for test
