iMath extension for LibreOffice

The iMath extension to LibreOffice (and Apache OpenOffice) enables numeric and symbolic calculations inside Writer and Impress documents. The development of iMath was prompted by a problem which I often encountered doing calculations in my profession as a mechanical engineer. I would first begin writing out the problem on paper, putting together the necessary equations, and then turn to a spreadsheet to do the actual calculations. iMath is meant to integrate this process in a single Office document.

Download and installation

iMath can be downloaded from sourceforge. You might also want to have a look at the CompPad project, and CmathOOoCAS which adds symbolic capabilities to calc. Both of these projects appear to be unmaintained, though.

Up to version 2.1.4, iMath makes use of the EQC library. Linux users will have to install this first.

Windows users might need to install the Microsoft Visual C++ Redistributable Package (search for "vcredist" on the Microsoft website). Please make sure to choose matching versions according to the information below!

If your operating system can install .deb packages, have a look at my PPA. Note that if your system does not have libginac6 with a minimum version of 1.7.1, you must install from the PPA. In this case the required version of libginac6 will be installed as well.
