ComplexMatrixPlugin 4.6 has a much more powerful testComplexMatrix project which produces the application MatrixCalc.
ComplexMatrixPlugin can be used for 32 and 64 bit Xojo applications.
ComplexMatrixPlugin for Xojo has all the functionality of my Complex and Matrix plugins and adds the ability to handle complex matrices and polynomials.
ComplexMatrixPlugin itself allows you to construct programs which can handle complex numbers, real matrices, and complex matrices much like doubles and integers are handled.
Many math functions can handle square matrices, such as Exp, Log, Sin, Asin, Sinh, Asinh, Pow, etc.
ComplexMatrixPlugin is compiled for Mac OS X, Windows, and Linux.
