## ## This function reorders (permutes) two matrices A and B which have the same shape so that their column structures are as similar as possible. The output value is the permutation order for the second matrix.
## ## WARNING: this function is slow!!
## ## NOTE: Currently not enabled in the main function "rNMF".
## per = function(A,B){
## fun1 = function(x){
## sum(apply(A - B[,x], 2, l2))
## }
## m = ncol(A)
## per = permn(m)
## diff = lapply(per, fun1)
## return(per[[which.min(diff)]])
## }
## "find.row" takes the (x,y) coordinates in A in the format xypair = c(x,y), and returns the corresponding row index of v.
## "find.x" takes the index of v, and returns the x coordinator in A.
## "find.y" takes the index of v, and returns the y coordinator in A.
find.row = function(xypair, p){
xypair = unlist(xypair)
return(p * (xypair[2] - 1) + xypair[1])
