Theorem m2cpmf 22655

Description: The matrix transformation is a function from the matrices to the constant polynomial matrices. (Contributed by AV, 18-Nov-2019.)

**Hypotheses**
Ref	Expression
m2cpm.s	⊢ 𝑆 = (𝑁 ConstPolyMat 𝑅)
m2cpm.t	⊢ 𝑇 = (𝑁 matToPolyMat 𝑅)
m2cpm.a	⊢ 𝐴 = (𝑁 Mat 𝑅)
m2cpm.b	⊢ 𝐵 = (Base‘𝐴)

**Assertion**
Ref	Expression
m2cpmf	⊢ ((𝑁 ∈ Fin ∧ 𝑅 ∈ Ring) → 𝑇:𝐵⟶𝑆)

Proof of Theorem m2cpmf Dummy variables 𝑖 𝑗 𝑏 𝑚 are mutually distinct and distinct from all other variables.
