This function is to transform from real-valued data into normalized data.

`norm.data(dt.ori, range.data, min.scale = 0, max.scale = 1)`

dt.ori

a matrix (\(n \times m\)) of the original data.

range.data

a matrix (\(2 \times n\)) containing the range of the data, where n is the number of variables, and first and second rows are the minimum and maximum value, respectively.

min.scale

the minimum value within normalization.

max.scale

the maximum value within normalization.
