| Computer algebra system - Wikipedia, the free encyclopedia (449 words) |
 | The study of algorithms useful for computer algebra systems is known as computer algebra. |
 | The run-time of numerical programs implemented in computer algebra systems is normally longer than that of equivalent programs implemented in systems such as MATLAB, GNU Octave, or directly in C, since they are programmed for full symbolic generality and thus cannot use machine numerical operations directly for most of their functions. |
 | Computer algebra systems began to appear in the early 1970s, and evolved out of research into artificial intelligence, though the fields are now regarded as largely separate. |
