scicos-HDL the install steps don't match what is there in the stable scilab or scicos programs does it still work? can I convert some math functions that work in scilab to verilog?

Scicos is now a separate project called ScicosLab. it is based on version 4.x of scicos. I have tried using scicos-HDL and found it to be lacking. Basically this was some grad students class project and doesn't seem to be well maintained. Also it is not part of the scicos consortium so I don't think you will get much support. But, I think it will install with ScicosLab 4.3 Dave would you think I could install it to xcos somehow? would their be a way to turn scilabs math equations I write into a model block in xcos then save it as a model of some sort then something else turn that model data into hdl? How about the c output any good results with that?

Assuming one needs to have a function returning false or true on each call in pseudo-random order.and using JavaScript native Math.random() method as the basis of the pseudo-randomness. Say the variants of such function are: getAnswer1() { var n = Math.round(Math.random()); return n ? true : false; } getAnswer2() { var n = Math.floor(Math.random()*2); return (n==2) ? true : false; } Leaving obvious practical testing by platforms aside: Is there are theoretical considerations that pseudo-randomness (predictability) of either of above will be better or worse than the o...

Hi, Why cannot I use this stmt: Math a=new Math(); The Java document does not say I cannot use it. Thanks.

Dear Users I have a function in MATLAB that I wanted to convert into Scilab. (read at the end of this post !) It involves a basic symbolic math application in MATLAB. I am in the process of moving away from MATLAB completely, so I am finding some problems during my migration. Can anyone point me in the right direction ? or atleast suggest a user manual that will give me some pertinent information.

Hi all, I've never found a satisfactory reply to this issue, which comes out every time I want to write some software library: suppose I wish to write it in one of my preferred languages, such as ocaml or haskell, but also that I want other people to be able to access it using their preferred languages, which might be ocaml, haskell, java or C++, for example. Is there a feasible route to do all this? Is there a simple way to write a library, where "simple" stands for "I have free time to write a library, not to write marshallers by hand", in ocaml or haskell, that will...

I can't find it. Can't find the file, though there's a documentation about it in the help (under the keyword "startup"). In scilab-4.1.1 it is simply located in <path2sci>/ In SCIHOME/.Scilab/scilab-5.0.2 there's no scilab.ini neither. So: how does it loads all its own libs first place? (in scilab-4.1.1, all is done from SCI/scilab.star) Now in order to load my own libraries or third parties ones such as SIP, I will create a scilab.star in SCI (for scilab-5.0.2).

Hello All, In my organization, I wish to use Scilab/Scicos for designing advanced Process Control and Optimization solutions. Currently we develop models in Matlab/Dymola (a front end for modelica), convert the model to C code and interface with the Distributed Control System (DCS). I wish to see whether it is possible to substitute Matlab/Dymola with Scilab. In this regard, I am keen on knowing more about the "code generation" facility in Scicos. In spite of a great deal of search, I have been unable to find much (english) documentation about this feature. Could the ...

In my attempts to solve boundary value problems, I came across the Fortran = code TWPBVP available here: http://www2.imperial.ac.uk/~jcash/BVP_software/= readme.php The authors have ported this (plus some other bvp code) to R, b= y providing some wrapper functions for it. I last used Fortran as a student a VERY long time ago, so my current knowle= dge is effectively zero. However - how easy is it to use Fortran within Sc= ilab, and what is the canonical method for doing it? ...

Hi. I'd like to learn MATLAB code for research purposes and for general professional development. I'd like to do it at home, and I don't have a MATLAB license, so I want to find out if it would be useful to practice MATLAB coding in SCILAB. Bear in mind I have absolutely zero knowledge in this department, so I just want to make sure I'm not heading in the entirely wrong direction. Since I'm starting from nothing, I'd probably be doing very basic things. Thanks for any help, Alex On 6/20/2015 2:28 PM, Alex Ritger wrote: > Hi. I'd like to learn MATLAB ...

For anyone that's getting tired of all the spam in this forum, I want to invite everyone to check out the new on-line community Scilab announced on their website a couple weeks ago (www.equalis.com). The site has a dedicated forum and interest group for scilab users - registration is free. Even though it's only been a couple weeks there are already questions being posted daily and 90% of the posts have at least a response. Looks promising. forum: http://www.equalis.com/forums/topics.asp?forum=95169& group: http://www.equalis.com/members/group.asp?id=63628 ...

I'm not a UNIX/Linux user, though with OSX I guess I am now. The installation calls for a number of additional files that I can't find and I'm expected to use "fink" to do something. Any help appreciated.

I want to write a OPC toolbox , but OPC(OLE for process) is designed based on COM, so it is better to write in c++ than c.

So now I can't do more , wish help me. also I want to ask another question: could I write dll using vc++, and find a way to let scilab using the dll, who can tell me how could I can let scilab using the dll which is builded by vc++(using c++ language, not C)? routines:export"c",extern"c",etc. can solve this problem? a...

Hi. What hardware description language used for developing modern CPUs? Does Intel and AMD using Verilog, VHDL or their own set of tools/languages? The OpenSPARC open-source CPU written in Verilog, so, UltraSPARC too? More designers use Verilog than VHDL, and some use systemC. ARM, MIPS and eSi-RISC are in Verilog AFAIK.

Hi group, I'd like to interface a scilab-function (which has many while-cicles) with a c-function and, in this c-function, do several calls to some others scilab functions (e.g. pinv(),rank() and user-defined functions). At the beginning, I tried with something simple like a c-functions without calls to scilab functions (e.g. a c-function containing only the statement WriteMatrix(some_vars)) and all was ok. Then, I tried to use the statement SendScilabJob("fun_name") and it failed every time! The error was mvfromto: stack size exceeded (Use stacksize function to increase it). So, I tried with stacksize(2^27) but nothing has changed! I use Scilab-4.0 stable version running on a Debian GNU/Linux Box etch/sid (32 bit). I really need to work out this trouble and I'd appreciate any suggestion you will give to me. These are the steps to reproduce the error: 1) CREATE THE TWO FILES (put these files in a SCI/test-dir/ directory): ------------------- | file ex1fi.desc | ------------------- ex1c a a scalar b scalar ex1c a b a double b double out sequence b *********************** --------------- | file ex1c.c | --------------- #include <math.h> #include <stdio.h> #include <string.h> #ifndef SCI #define SCI ".." #endif #define TRUE 1 #define FALSE 0 #include "../routines/machine.h" #include "../routines/stack-c.h" #include "../routines/system/C...

Hi all, Here I wanna use sas to solve a interesting math problem as follow: There are nine numbers 1 2 3 4 5 6 7 8 9 and you can put multiplication, addition ,subtraction and division between any two numbers and let the result equals to 1/5. I wanna see how many ways there exists to realize this. How can I express this in sas code?=20 =20 Many thanks, =20 Mu Mu Mu Mu you can quickly rule out multiplication, addition ,subtraction since your nine numbers are integers. You remain with division and your problem is reduced. Also since 1/5 is < 1, the numerator in the division ...
