Hi Uni,
For some reason, I always have the same error, using mwfprintf() function.
It looks the same on both 32-bit and 64-bit Windows.
Could you explain what is wrong here ?

Hi Igor.

There is a log.txt in the plugin directory: \extensions\plugins\4c2faab1-4d93-4904-8d88-a4e21512d179\1.0.4987.26944\
If you look at the contents, you will see errors when working with functions.

In this case, we see a problem in converting the operation result. Probably something has changed in the SMath Studio and my examples stopped working correctly.

mwfprint() works fine, but you need to set the current folder or absolute path. The error occurs after running the function while trying to return the result of work in bytes.

I will try to fix the error, if I can. Now I don't have the latest source.

Updated. Try now (with SMathStudio_Desktop_0.97.5189_32bit.exe for 64-bit).

I'm curios to know -
There is a plugin for using Maxima and a plugin to use Matlab/C++, is there advantage to starting using one over another? I mean is one more/less powerful. Is one better with units or symbolic?

Thanks!

Updated. mwfscanf() now working too. Relative path also works. Strings as parameters not supported for now.

You can get these plugins from the Extensions Manager (I don't know how it called in english). They are very different. Matlab C++ Math Library - just a numeric library, not symbolic. Full description you can get from the MATLAB C++ Math Library. User's Guide. Version 2.1.pdf. Also, no need to install Matlab.

Advantages of the matlab lib plugin:
  • more functions
  • more uniform and consistent function interface
  • better documentation (you can use original matlab docs in the web )
  • easy installation (just download the plugin)
  • certainly more performant numerics (did not benchmark this)

Advantages of the Maxima plugin
  • symbolic math
  • units handling
  • safe legal status
  • graphics functions (matlab has better ones, but they are not exposed to SMath in the plugin)

Hi Uni,

I would use the svd-function from the matlab c++ Math Library.
But the function is not available.


Thanks and best regards

The fact is that not all functions realized. Only blue ones with the mw prefix exist.

Updated. svd() added, but I'm not shure about how it works (correctly or not).

I think something is wrong here. U matrix has extra column and S matrix should bi diagonal.

I see. Thank you uni. I thought on [U,S,V] = svd(X,0) only.

Что обозначает в заглавном посте зеленый и синий цвет функций. Зеленые smath не "видит". Как заставить его их увидеть? Спасибо.

Синие с префиксом mw реализованы, остальные ещё нет (по запросу), поэтому они не видны.
