Thanks for sharing this package.Is there any support about fft function?

Hi, Is there any support for sparse matrix from the Matrix/matrix class in this library?

We seen a constant increasing memory usage when used MatrixSolve from our code. The below example show how we used the library which cause an extra Matrix allocated and never freed (Ea in the evaluate method as that got a copy of A which never freed).

int n = 400;
matrix ax = new matrix(n, n);
matrix b = new matrix(n, 1);
for (int i = 0; i < 10000; i++)
{
      MatrixSolve solve = new MatrixSolve(ax, b);
      matrix result = solve.Evaluate();
      result.Dispose();
}
ax.Dispose();
b.Dispose();

After this point we have 10000 extra 400*400 double array in the pool which never returned.
Is there a better way to use this method with direct matrix input?

Hi,

I'm probably missing something obvious but for example MKLNET.Vml.Asin(Values, Result1); results in:

System.DllNotFoundException
HResult=0x80131524
Message=Unable to load DLL 'mkl_rt.dll' or one of its dependencies: The specified module could not be found. (0x8007007E)
Source=MKL.NET
StackTrace:
at MKLNET.Vml.vdAsin(Int32 n, Double[] a, Double[] r)
at MKLNET.Vml.Asin(Double[] a, Double[] r)

I've add MKL.NET + Matrix + Optimization + Statistics and the only native dependency seems to be MKL.NET.Native.dll.
Should mkl_rt.dll be distributed with your package or is it something I have to install separately?

Hi, I am having the following issue where one of the DLLs is not being built.

Using MKL.NET with the following versions:

MKL.NET 1.4.0
MKL.NET.Matrix 1.0.0
MKL.NET.win-x64 2022.0.0.115

I've been able to do some matrix and vector operations with no worries, but calling in to the C API does not work.

System.DllNotFoundException: Unable to load DLL 'MKL.NET.Native.dll' or one of its dependencies: The specified module could not be found. (0x8007007E)
   at MKLNET.Dfti.ComputeForwardInplace(Int32 n, Complex[] x_inout)
   at MKLNET.Dfti.ComputeForward(Complex[] x_inout)
   at Filtering.Fft.Resample(Double[] xs, Int32 num)

I have tried building Debug & Release for x64 & any-cpu targets.

I'm sorry if this turns out to be a stupid question, I just can't find any documentation for how to fix it myself.

Thanks.

Hi,

First of all: thank you for your work on this great library! I am currently toying around with it and so far I do really enjoy using it!

I am currently working on some .Net CLI tools which reference the MKL.Net core package as well as the windows and/or linux runtime and I noticed that their size (runtimes) is rather large. This has the effect, that any CLI tool using the linux runtime is >250mb in size and can therefore not be hosted on nuget.org.

Unfortunately, dependencies can not be included into cli tools by reference, but are included upon build, so the only workaround I can come up with is to shrink the size of the referenced runtimes. Do you think it would be possible to do so?

Other than that, I wondered whats the rational behind MKL.NET.linux-x64.b, which is referenced by the linux runtime.

Cheers

Is there any support about Special Functions like bessel function in this package?

is there any function about svd like in matlab?

[[U,S,V] = svd(A)]
[[U,S,V] = svd(A,'econ')]

Just an idea, since you already have a build pipeline in place for packaging cross-platform libraries (and maybe for generating the P/Invoke boilerplate, although maybe that is handcrafted?)

We've had good experiences with Intel's other library IPP (Integrated Performance Primitives), it offers some functionality that MKL lacks like vector-scalar binary operations (e.g. add constant to vector), threshold operations and more.

It might be out of scope for this project, just tell me what you think. I might be able to contribute some P/Invoke definitions if you're interested, subject to my employer's permission.

Would it be possible to access to Spline1D in the future ?

Make the matrix operation work over more matrix shapes:

https://numpy.org/doc/stable/user/basics.broadcasting.html

Stride was added to MKL to do this:

https://software.intel.com/content/www/us/en/develop/articles/new-mkl-vml-api.html

Also things like Matrix.Max(M, 0.0)

Is there a way to control Matrix storage in terms of being RowMajor or ColumnMajor?

As far as I can tell there is only 1D fft support.

Any chance of 2D being supported in a future release?

band storage type matrix and function ''_gbrts, _gbrtf, .....' being supported in a future release?

Hi just found this awesome library and I cant find some mkl functions (especially mkl_malloc).
Does this library exposes all mkl functionality?
If so how does I find this function?
And if not can I access the native function and wrap in myself using this library (for the installation of mkl).

Thanks in advance.

This library looks very interesting, however, in our apps we also use a lot of single precision matrices and vectors shave off some memory usage. Would it be possible to add a single precision matrix and vector types?

I am trying to use your package to do SVD on a large matrix. However, I am having trouble getting a simple matrix to execute. Here is the code:

            int m = 3; // Number of rows
            int n = 3; // Number of columns
            double[] a = { 1, 2, 3, 4, 5, 6, 7, 8, 9 }; // Input matrix
            double[] s = new double[Math.Min(m, n)]; // Singular values
            double[] u = new double[m * m]; // Left singular vectors
            double[] vt = new double[n * n]; // Right singular vectors
            double[] superb = new double[Math.Min(m, n) - 1]; // Array for additional information

            int info = MKLNET.Lapack.gesvd( MKLNET.Layout.ColMajor, 'A', 'A', m, n, a, n, s, u, m, vt, n, superb);

When the code executes the gesvd line - the program crashes. No error - just stops running.

Any idea on what I am doing wrong?
Thanks for the help!

Hi,

First of all thanks for this library, it's really helpful to have the P/Invoke definitions available like this.

I wanted to ask whether it is possible to provide the MKL functions with double*,int signatures instead of double[]. Actually just making the original extern declarations public would be enough.

It would be really useful for example with pointers from memory-mapping or when I want to access only parts of an array.

Thanks and cheers

Hi,
I tried to build the project and in order to do so I executed the buildNative.ps1 script locally.
It seems like there is a problem unzipping some .nupkg files in the script.

The error massage:

Expand-Archive : .nupkg is not a supported archive file format. .zip is the only supported archive file format.

The current DLL name is mkl_rt.2.dll. Theres no way to update the DLL variable that holds this without rebuilding.

#if LINUX
internal const string DLL = "libmkl_rt.so";
#elif OSX
internal const string DLL = "libmkl_rt.dylib";
#else
internal const string DLL = "mkl_rt.dll";
#endif

And its a FREAKING CONST So its baked in to the compile. Cant change it at runtime!!! whyyyyyy????

Your runtime nuget packages are old (2022) so I want to use the current MKL, so I would rather just be able to have path set up to it, but i cant change the damned DLL name in your library.
