Swap two columns in a matrix
This functionality does not run in MATLAB.
linalg::swapCol(A, c1, c2) linalg::swapCol(A, c1, c2, r1 .. r2)
linalg::swapCol(A, c1, c2) returns a copy of the matrix A with the columns with indices c1 and c2 interchanged.
The effect of linalg::swapCol(A, c1, c2, r1.. r2) is that only the components from row r1 to row r2 of column c1 are interchanged with the corresponding components of column c2.
We consider the following matrix:
A := matrix(3, 3, (i, j) -> 3*(i - 1) + j)
The following command interchanges the first and the second column of A. The result is the following matrix:
linalg::swapCol(A, 1, 2)
If only the components in the first two rows should be affected, we enter:
linalg::swapCol(A, 1, 2, 1..2)
The third row remains unchanged.
