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