Missing factor when removing elements in sparse complex matrix.

[abulvenz]

Hey there,

In sparse complex matricies you get an ArrayIndexOutOfBounds error, when an element (although existing) is removed, because it turns 0.0.

This line is causing the problem:

ParallelColt/src/main/java/cern/colt/matrix/tdcomplex/impl/SparseRCDComplexMatrix2D.java

Line 1232 in 36a75e6

valuesList.setSizeRaw(rowPointers[rows]);

It should look like this line:

ParallelColt/src/main/java/cern/colt/matrix/tdcomplex/impl/SparseRCDComplexMatrix2D.java

Line 1218 in 36a75e6

valuesList.setSizeRaw(2 * rowPointers[rows]);

Because it is complex the matrix contains twice as many elements.

If you prefer a PR please let me know.

Ciao
Andi

Hi @abulvenz,

I created a fork that fixes this bug and another one I found after this.

Unfortunately I don't know how to publish it via maven.
