Matlab's lp() function

[Hans Zoebelein]

Supporting my fight with a simple looking script which was
written for Matlab, "John W. Eaton" <address@hidden>
sent me his 'spconvert.m' function file which should resolve 
one problem.

The last lock which has to opened before OCTAVE can digest this 
script, seems to be the use of Matlab's 'lp()' function. 
Matlab's online manual says:

        LP      Linear programming.
        X=LP(f,A,b) solves the linear programming problem:
        min f'x    subject to:   Ax <= b 
         x

        [x,LAMBDA]=LP(f,A,b) returns the set of Lagrangian multipliers,
        LAMBDA, at the solution.

        X=LP(f,A,b,VLB,VUB,X0) sets the initial starting point to X0.
        X=LP(f,A,b,VLB,VUB,X0,N) indicates that the first N constraints
        defined by A and b are equality constraints.

YUCK! There seems to be no lp() function under OCTAVE. Would it be
possible, to simulate Matlab's lp() function?


Enjoy!
