Matrix Toolkits for Java (MTK) doesn't play well with 64 bit Windows #59

Closed jdramsey closed 9 years ago

jdramsey commented 9 years ago

If imports starting with no.uib.cipr.matrix are commented out, the problem code is put in red in IntelliJ. Classes affected are IndTestHsic, KernelUtils, Ling, Lingam.

The compiled classes seem to run OK, but the relevant tests break when run in Maven.

I think we should support 64 bit Windows. If so, need to translate this matrix algebra to a different library.

jdramsey commented 9 years ago

I've worked on Ling and now Lingam, trying to substitute the Apache matrix library for the MTJ library. The only thing missing is a QL decomposition; I've substituted QR, but I have to think that through.

ekummerfeld commented 9 years ago

IndTestHsic appears to be using the following from those imports: Matrix objects made either with Matrix or DenseMatrix, e.g. "Matrix Kyx = new DenseMatrix(m, m);" some functions built into the Matrix object class, such as matrix multiplications, e.g. "Ky.mult(Kx, Kyx);" and .get and .numcolumns and .transpose and .copy and .set and .solve Matrices is also used e.g. "Gztzr.solve(Matrices.identity(kz), ZI);"

jdramsey commented 9 years ago

Actually all of those are doable; that might be easier than Ling to translate, although I recall there being a lot more red stuff.

jdramsey commented 9 years ago

Solve is just inverse.

ekummerfeld commented 9 years ago

That's all the red stuff that I found but I might have messed something up. Gonna do a fresh clone and intelliJ project and look again.

jdramsey commented 9 years ago

Hold on, I didn't push the stuff I just did. Give me a couple of minute.

jdramsey commented 9 years ago

OK should be there.

ekummerfeld commented 9 years ago

I just reran the maven tests and this was the result:

Tests in error: testIncompleteCholesky(edu.cmu.tetrad.test.TestIndTestHsic): unable to load from [netlib-native_system-win-x86_64.dll] test6(edu.cmu.tetrad.test.TestLing): column index (5)

Tests run: 439, Failures: 0, Errors: 2, Skipped: 0

ekummerfeld commented 9 years ago

In addition to the no.ui etc. imports that get red, TestIndTestHsic has another import that gets red.

import junit.framework.TestCase; import no.uib.cipr.matrix.DenseMatrix; import no.uib.cipr.matrix.Matrices; import no.uib.cipr.matrix.Matrix;

All of those imports get redded out.

I think I fixed everything. Could you try cloning again and running mvn test? It passes for me but hoping it passes for you.

jdramsey commented 9 years ago

By the way, when you go to work on the project, could you fork it and work on the fork instead of just a clone of the master repository? That way you can issue pull requests, which are a lot safer.

HA! Nice. You are now compatible. :)
