Re: Linear Programing

[g940100]

Hello all,

   I tryed "octave-2.1.31" and "semidef". It seemed to go quite well,
but at the end an error happened. The messeges are these;

======================================
octave:1> demosp
Octave implementation of Vandenberghe and Boyd's semidef package

  [ 1] educational testing problem
  [ 2] linear programming
  [ 3] matrix norm minimization
  [ 4] stability margin problem
  [ 5] quit

pick a number, any number: 1

educational testing problem: maximize the trace of a diagonal
matrix D > 0 such that A - D >=0 for a given positive definite
matrix A

Command: help etp
Press a key to execute command  executing
etp is the user-defined function from the file
/home/hatibee/src/octave/semidef-octave-2.1/SRC/etp.m

[d,Q] = etp(A);

   Do you know why it does not work well?
