If your system has more unknowns than equation (after gbasis computation), it is solved with respect to the last unknown(s) it depends on, regarding the first "unknown(s)" as parameters, and solve happens in the generic situation. Sir, Could you direct me to the place where I can download the latest manual(s) for XCAS, English and/or French it doesn't matter. Thank you. |
