newbie question: howto prepare data for processing (i.e.: conv/deconv)

[h....@web.de]

Hi all,

I try to compile some testcode with Win7 Pro, Visual Studio 2010 Pro, boost 1.58.0 and Boost.NT² 3.1.0. Sadly, it fails to compile.

The testcode is based on the following MATLAB example:

http://de.mathworks.com/help/matlab/ref/deconv.html

What am I doing wrong?

#include "stdafx.h"

#undef min

#undef max

#include <boost/simd/memory/allocator.hpp>

#include <vector>

#include <nt2/table.hpp>

#include <nt2/core/functions/tie.hpp>

#include <nt2/polynom/functions/conv.hpp>

#include <nt2/polynom/functions/deconv.hpp>

#include "de_conv.h"

void de_conv()

{

typedef std::vector<double, boost::simd::allocator<double>> aligned_vector;

aligned_vector vu(4);

vu[0] = 1.0;

vu[1] = 2.0;

vu[2] = 3.0;

vu[3] = 4.0;

aligned_vector vv(3);

vv[0] = 10.0;

vv[1] = 20.0;

vv[2] = 30.0;

nt2::table<double> tu(&vu[0], &vu[0] + vu.size());

nt2::table<double> tv(&vv[0], &vv[0] + vv.size());

nt2::table<double> tq, tr, tc;

NT2_DISPLAY(tu);

NT2_DISPLAY(tv);

tc = nt2::conv(tu, tv);

nt2::tie(tq, tr) = nt2::deconv(tc, tu);

NT2_DISPLAY(tc);

NT2_DISPLAY(tq);

NT2_DISPLAY(tr);

}

The error is as follows: (cannot switch to english language, but the error looks like a usual stupid newbie mistake:)

As stated int he documentation, the first one are basically forward declaration. The second brings in the require dimplementation with respect to your machine settings.

I think this kind of error is usually a problem with the compiler not
handling C++11 correctly.

Can you try with master?

Your issue with construct is maybe related to the fact table constructor
from range expect a extent (ie a nD boundaries) object as first parameter :

float data[] = { 1,2,3, 4,5,6 };

table<float> x( of_size(3,2), &data[0], &data[0] + 6 );

[h....@web.de]

Just for the record, I tried to compile my testcode with Visual Studio 2015 RC community edition instead.

The result is the very same error as with VS2010.

Is there somewhere a package for nightly builds?

If not, do I have to compile master and create a package myself?

If so, compilation failed with Visual Studio 2010 Win32/Release target at:

nt2-master\modules\boost\dispatch\include\boost/dispatch/meta/hierarchy_of.hpp(76)

And at another location. It does not like using-statements.

I will retry with Visual Studio 2015 RC. Let's see...

Kind regards,

Yes, I had a look at: nt2/core/functions/table/construct.hpp

And I guess this version looks ok to compile:

nt2::table<double> tu(vu.size(), &vu[0], &vu[0] + vu.size());

Another problem I just found is that my memory could be exhausted(4GB where windows uses nearly 2GB already).

I guess I better find a better system first before further testing ...

Thank you very much!

Kind regards,

Hanno Meyer-Thurow

The way you initialize the data make it so the vector data are copied
back into the table. Either just allocate the table and fill it in or
use the shared_ constructor that will just reference data :

table<float, nt2::shared_> tu(of_size(1,n), nt2::share(&vu[0], &vu[0] +
vu.size()));

[h....@web.de]

Okay, that would be the next step. Thank you, again!

I just compiled master with Visual Studio 2015. Sadly, there are missing headers in nt2/include/...

For example, nt2.core.polynom is missing completely. Which would have shipped the functions conv/deconv.

did you rerun your cmake to regenerate the headers ?

[h....@web.de]

I generated the project files for Visual Studio 2015, built the Win32/Release project map via 'F7',

60 projects succeeded and finally built the package.

How do I regenerate the headers?

[h....@web.de]

Attached you find the current source file and compiler log for: Visual Studio 2015 and nt2 v3.1.0.

The tables are constructed but it chokes on conv/deconv functions. Any ideas?

I finally got around to test the code on my linux box.

The result is not any better, sadly. The specs are:

Finally got master built as it should on my linux box.

That, you do not want to do under Windows.

Looks much better! But now, I get gcc ICE with gcc-4.9.2 and gcc-5.1.0.

Log is attached.

Okay, gcc/c++11 does not like the boost type traits.

I changed the type traits of boost.simd.native header to c++11 ones and nt2::conv compiled and works(results as in MATLAB example).

nt2::deconv is not that trivial to fix; a simple replace failed to compile.

I guess I will retry once you changed the type traits to c++11 implementation.

Would be great if you notice me then.

Kind regards,

[Joel FALCOU]

I'll gladly accept a patch for that. We din't put 4.9/5.x on our test
bot yet. We probably should.

[h....@web.de]

Well, as soon as you go c++11-only you do simple sed/awk commands to switch, at least for type traits.

For now, I have done my tests and the nt2 library looks promising for my needs!

Kind regards,
