Example 3 : Member functions

Note: these functions are present as a convenience only. All functions are also available globally.

Submatrix (member) functions

Extraction of sub matrices and sub vectors of any kind from a large matrix:

import arrlib as arr

m = arr.xyzfMat(10,10)

b = arr.box2i((1,1),(4,5))
subm1 = m.subMatr(b)

b = arr.box2i((0,0),(10,10))
subm2 = m.decimateMatr(b,2,3)

r = arr.uintVec(2)
c = arr.uintVec(2)
r[0]=2,r[1]=4
c[0]=3,c[1]=5
subm3 = m.indexedSubMatr(r,c)

rowvec = m.rowVec(3)
colvec = m.colVec(5)
ro = m.rotateMatr(1)

The parameter to rotateMatr is:

0: no rotation
1: 90 degrees counterclockwise
2: 180 degrees counterclockwise
3: 270 degrees counterclockwise

The subVec functions are similar, but in one dimension.
