If one converts this row of the matrix back to equation form, the result is which does not make any sense. It is the successor to the 40G, and 38G, and it is sold alongside the 39gs (equivalent with infrared but without CAS). The RREF will be [I3jx] for some x (the matrix [v1 v2 v3] has nonzero det, so its RREF is the identity matrix). They are clearly independent. You can add, subtract, multiply and transpose matrices. Partial pivot with row exchange is selected. Easily perform matrix multiplication with complex numbers. ) The first and second columns are pivot columns, so variables x 1 and x 2 are basic variables. I've been just winging it up until now, but I have an exam tonight and I don't want to spend all the time on a few problems. Recall that a pivot column is all zeros, except a single one.
