The unknowns should be in the domain [0,1]. That is the only contraint. Even though I give feasible start point that satisfies the equations and contraints, the optimization display says infeasible start point. Most of the times even though it says infeasible start point it performs the iterations and converges. What does this mean? Thank you, Pranitha Hi,

I have a problem to run my optimization code. Perhalps I don´t know the rights steps. I look the optimization toolbox but it doesn´t work. I´m trying to run one code of minimization cost of irrigation network with a lot of variables. Could you help me send me one code using the OPTIMTOOL for function objective (with a lot of variables) and another for constrains? Thansk a lot for your attention! Hello Hull!

It taught me that publication is a good way to make your work available to the world. Then Kodak moved into the mode of first asking whether any idea should instead be patented. So I earned a few patents in my name, but I never was happy with that idea. Once I retired, I realized that the file exchange on Matlab Central is really a publication tool for high quality software. Much like any journal, your work will be reviewed by your peers, but paper journals do the reviewing in advance of publication. The file exchange allows fully public peer reviews. Since you also have the ability to update and enhance your codes, those reviews help to provide world class codes. There are some truly top notch codes to be found on the file exchange, and I feel privileged to be able to contribute my own work to that mix.

To compensate him for his many continuing contributions, John should be able to get a MATLAB license just like book authors do. If you need justification, call this pick of the week a book. It is great! John is an all-around top notch contributor to cssm, FEX, and the MATLAB wiki.
