Hypotheses

Ref	Expression
d1mat2pmat.t	⊢ 𝑇 = (𝑁 matToPolyMat 𝑅)
d1mat2pmat.b	⊢ 𝐵 = (Base‘(𝑁 Mat 𝑅))
d1mat2pmat.p	⊢ 𝑃 = (Poly1‘𝑅)
d1mat2pmat.s	⊢ 𝑆 = (algSc‘𝑃)

Assertion

Ref	Expression
d1mat2pmat	⊢ ((𝑅 ∈ 𝑉 ∧ (𝑁 = {𝐴} ∧ 𝐴 ∈ 𝑉) ∧ 𝑀 ∈ 𝐵) → (𝑇‘𝑀) = {⟨⟨𝐴, 𝐴⟩, (𝑆‘(𝐴𝑀𝐴))⟩})

Proof of Theorem d1mat2pmat

Dummy variables 𝑖 𝑗 are mutually distinct and distinct from all other variables.
