preprocessDataInit: Data Preprocessing

In ZahraSajjad/ElasticMap: Elastic Map Fitting

Description

the function to perform data preprocessing . to calculate map principal components (Orthonormal Matrix)

Usage

preprocessDataInit(map,data,reduce)

Arguments

map	a list that was created by Map Geometry Functions rect2Dmap
data	The data is n-by-m matrix with m data points and n coordinates for each point (each column is one data point)
reduce	is integer. If reduce is positive and is less than n then specified number of the first principal components are used. If 'reduce' is zero and m>n then the first n-1 principal components is used. If 'reduce' is positive and is greater or equal to n or 'reduce' is zero and n>m then dimensionality reduction is not performed. If reduce is negative then reduce PCs are calculated but dimensionality reduction is not performed

Value

A list with two variable:

map	update map that was created before with map geometry function, add value to map Pcs
data	is the result of data preprocessing after we calculate principal components of map. we call preprocessData

function to calculation.
