Computes the directions.

Syntax

m = optimsimplex_dirmat(opt)

Argument

opt

The current simplex object of TSIMPLEX type (tlist).

m

A n-by-n matrix of doubles.

Description

The optimsimplex_dirmat function returns the matrix of simplex directions, i.e. the matrix of differences of vertices coordinates with respect to the vertex #1.

Example

s1 = optimsimplex_new ();
simplex = [
3.  1.  1.
4.  1.  1.
5.  0.  2.
];
s1 = optimsimplex_setall ( s1 , simplex );
m = optimsimplex_dirmat ( s1 );
disp(m)

s1 = optimsimplex_destroy(s1);
