If it gives the following, then everything is ok: fmlpsolve FreeMat Interface version 5.5.0.6 To test if everything is installed correctly, enter fmlpsolve in the FreeMat command window. There are also some FreeMat script files (.m) as a quick start.
FREEMAT MAKE X A VARIABLE DRIVER
So note the difference between the FreeMat lpsolve driver that is called fmlpsolve and the lpsolve library that implements the The shared library must be somewhere in the Windows/Unix/Linux path.
FREEMAT MAKE X A VARIABLE UPDATE
This has the advantage that the fmlpsolve driver doesn't have toīe recompiled when an update of lpsolve is provided. This driver calls lpsolve via the lpsolve shared library (lpsolve55.dll under WindowsĪnd liblpsolve55.so under Unix/Linux) (archive lp_solve_5.5.2.5_dev.zip/lp_solve_5.5.2.5_). This driver must be put in a directory known to FreeMat and FreeMat can call the fmlpsolve solver. To make this possible, a driver program is needed: fmlpsolve (fmlpsolve.dll under Windows, fmlpsolve.so under Unix/Linux). To be optimized may be numerically complicated in which case a software package likeįreeMat is required to effect a solution. The constants in the linear inequalities or the object expression for the quantity Indeed these techniques are often taught in high school or university levelĬourses in finite mathematics. But sometimes these numbers are high, or even if low, Of constraints are small, then there are numerous mathematical techniques for solving a That you want to maximize or minimize subject to several constraints that are expressedĪs linear inequalities in the same variables. If the number of variables and the number These are problems in which you have a quantity, depending linearly on several variables, See further in this article.įreeMat is ideally suited to handle linear programming problems. Script files that can make things a lot easier. If you find that this involves too much work to solve an lp model then you can also work via higher-level
FREEMAT MAKE X A VARIABLE FULL
So you have full control to the complete lpsolve functionality via the fmlpsolveįreeMat driver. The whole lpsolve API is implemented with some extra's specific forįreeMat (especially for matrix support). Is written in C so it has maximum performance. Matrices can directly be transferred between FreeMat and lpsolve in both directions. As such, it looks like lpsolve is fully integrated Lpsolve is callable from FreeMat via an external interface or Import. We will not discuss the specifics of FreeMat here but instead refer the reader to theįreeMat Google Discussions and the FreeMat primer overthere. In addition to supporting many MATLAB functions and some IDL functionality, it features a codeless interface to external C, C++, and Fortran code, further parallel distributed algorithm development (via MPI), and has plotting and 3D visualization capabilities. It is similar to commercial systems such as MATLAB from Mathworks, and IDL from Research Systems, but is Open Source.įreeMat is available under the GPL license. Using lpsolve from FreeMat Using lpsolve from FreeMat FreeMat?įreeMat is a free environment for rapid engineering and scientific prototyping and data processing.
