0.42

• MatrixIO
  • Fixed Matrix Market save. Thanks Adam Logowski for pointing out the issue
  • Vector matrices are supported in matrix market.
  • Removed unsafe and deprecated functions loadBin() and saveBin()
• Negative rows or columns are now illegal
  • Thanks JozsefKutas for pointing out the issue
• Complex Matrix Support
  • Added elementMultiply(mat, mat, mat)
  • Added elementDivide(mat, mat, mat)
  • Added elementPower(math, real, mat)
• ConstMatrix
  • Interface that only implements operations that are read only.
  • Requested by many People
• SimpleMatrix
  • Thanks JozsefKutas for getting this needed refresh started
  • Removed deprecated functions
  • Updated JavaDoc
  • API Consistency: getNumRows, getNumCols
  • Added getRow(), getColumn(), setRow(), setColumn() that works with SimpleMatrix directory and handles all types.
  • Added stripReal() and stripImaginary()
  • Added conjugate() and magnitude()
  • Added fillComplex(), transposeConjugate(), sumComplex(), determinantComplex(), traceComplex()
  • Added elementOp(()->{}) for real and complex matrices. Allows user defined element wise operators.
  • Added simplified functions to create random matrices
  • Modified concurrent trigger to take in account size of both input matrices
• CommonOps_DDRM
  • Added elementBoolean(matrix, lambda) for arbitrary element-wise boolean operators
• MatrixMatrixMult_ZDRM
  • Added concurrent versions of several matrix multiplication ops
• Handling of zero sized matrices
  • Unit tests ensure decompositions and linear solvers can process 0x0, Mx0, 0xN matrices.
  • Requested by JozsefKutas and others. Note: I've never personally had a desire for this...
  • Only rigorously tested with DDRM
• ConvertMatrixData
  • Can now convert boolean matrices into different data types
• Various
  • Ops classes with all static members now have private constructors to drive home the concept of static functions.
