Using the DataMatrix object

This example shows how to initialize a DataMatrix object, store it to a file and then to restore it back.

from pysgpp import *

Create a 2x2 matrix

m = DataMatrix(2,2)
m.set(0, 0, 1.0)
m.set(0, 1, 2.0)
m.set(1, 0, 3.0)
m.set(1, 1, 4.0)

Store the matrix to file

m.toFile("dataMatrixTest.mat")

Load the created DataMatrix from file and then save it again (for no particular reason)

m2 = DataMatrix.fromFile("dataMatrixTest.mat")
m2.toFile("dataMatrixTest2.mat")
