∀[n,m:ℤ]. ∀[r:RngSig]. ∀[i,j:ℕm]. ∀[M:Matrix(n;m;r)]. (matrix-swap-cols(M;i;j) ∈ Matrix(n;m;r))
Proof
Definitions occuring in Statement :
matrix-swap-cols: matrix-swap-cols(M;i;j),
matrix: Matrix(n;m;r),
int_seg: {i..j-},
uall: ∀[x:A]. B[x],
member: t ∈ T,
natural_number: $n,
int: ℤ,
rng_sig: RngSig
