Maxima Function
copymatrix (M)
Returns a copy of the matrix M. This is the only way to make a copy aside from copying M element by element.
Note that an assignment of one matrix to another, as in m2: m1
,
does not copy m1
.
An assignment m2 [i,j]: x
or setelmx (x, i, j, m2
also modifies m1 [i,j]
.
Creating a copy with copymatrix
and then using assignment creates a separate, modified copy.
