In short, I do not order because I do not know the priorities. Now, if you ask me to risk an opinion, not a request, I think that what should be prioritized is to have a robust and predictable numerical linear algebra library.

For your information, the DotNumerics plugin contains the sources of the LAPACK library. In theory, I can add some of the functionality of this library to the plugin. If someone needs a function from this library, then I can make it available.

Hi Viacheslav . Thank you very much, it is great that SMath has the possibility of having the libraries that you mention, especially LAPACK. But I think that the most basic functions should already be incorporated into the core of the program such as svd, such as one for svd and some other decompositions, functions similar to filter, find and max from matlab and some improvements in rank and det. I don't think there will be many in the end, but it would be a major improvement in the program. The major update was done with the ranking assignation, which make SMath not only as Mathcad substitute but a matlab alternative in education for some applications involving the concept of vectorization.

Best regards.
Alvaro.

But that before the update for Mathcad 11 2a. This version was hard to crack, and students have the previous version 11 2b, without NaN, or next releases, where mathcad starts it's dead, but all of them with NaN. Now 11 2a release it's dead because it's hardware authentication involving the net card and how know what's else.

Best regards.
Alvaro.

Ehh.. the last version of MC11.2 was an easy crack. It is just two bit to change if I remember correct. And this will bypass any check.

And I am still running my special MC11.2SG (stands for supergood - a slightly better Maple there) but it is in Danish (yep, translated it as well even with and option for the decimal separator to be , instead of .) It even works with the Excel and Smartsketch plugins (not smooth but workable) in win 10.

Last year I made a British version on request so if someone really would love to have a running MC11.SG UK version ... I will be surprised if Uni doesn't have something similar.

Smath has the vector field from Alvaro ...
No need MCD 11 cracked version.
What are you suggesting wrt Smath ?

Hi. A variation, consisting of a function similar to matlab's quiver, in which the vectors originate at the point considered, not as tangents at their midpoint.
