Description: Entries of a literal matrix. (Contributed by Thierry Arnoux, 28-Aug-2020.)

**Hypotheses**
Ref	Expression
lmatfval.m	⊢ 𝑀 = (litMat‘𝑊)
lmatfval.n	⊢ (𝜑 → 𝑁 ∈ ℕ)
lmatfval.w	⊢ (𝜑 → 𝑊 ∈ Word Word 𝑉)
lmatfval.1	⊢ (𝜑 → (♯‘𝑊) = 𝑁)
lmatfval.2	⊢ ((𝜑 ∧ 𝑖 ∈ (0..^𝑁)) → (♯‘(𝑊‘𝑖)) = 𝑁)
lmatfval.i	⊢ (𝜑 → 𝐼 ∈ (1...𝑁))
lmatfval.j	⊢ (𝜑 → 𝐽 ∈ (1...𝑁))

**Assertion**
Ref	Expression
lmatfval	⊢ (𝜑 → (𝐼𝑀𝐽) = ((𝑊‘(𝐼 − 1))‘(𝐽 − 1)))
