NumericalCertification :: identityIntMat

identityIntMat -- compute the identity diagonal interval matrix.

Description

A diagonal matrix with "[1,1]" as a diagonal entry is worked as a identity matrix in interval arithmetic.

For given positive integer "n", this function constructs the identity interval matrix of size "n".

i1 : identityIntMat 3

o1 = {{[1, 1], [0, 0], [0, 0]}, {[0, 0], [1, 1], [0, 0]}, {[0, 0], [0, 0],
     ------------------------------------------------------------------------
     [1, 1]}}
