| Post subject: | Compiled matrix functions for Excel |
Following a discussion in the EngTips Forum : http://eng-tips.com/viewthread.cfm?qid= ... amp;page=1 I have compiled the C++ versions of a number of matrix functions from the AlgLib library as a dll, and linked them to Excel. The spreadsheet and associated code can be downloaded from: http://newtonexcelbach.wordpress.com/20 ... for-excel/ The functions included are: Inverse of real matrix Inverse of complex matrix Determinant of real matrix Determinant of complex matrix Transpose of real matrix Transpose of complex matrix Matrix multiplication; real Matrix multiplication; complex Add matrices Extract matrix Insert Matrix Eigen value and Eigen vectors Solve system of linear equations I'd really like to get some feedback on this. Do the functions work correctly? Is the documentation adequate? What other functions would be desirable? Any problems installing the dll and linking to the spreadsheet? etc. |

Good work! I want to implement something like that several month later, but in my usual fashion - using automatic code generation :) All ALGLIB functions will be implemented as calls to C DLL. As for you project, I think that some convenient interface for reading matrices from text files (and for saving matrices to files) could be very useful. |
