2×2 Matrix Scalar Product Entry Calculator
2×2 Matrix Scalar Product Entry Calculator — change the supplied values to calculate 2×2 matrix scalar product entry.
Real 2×2 matrix, one selected entry only; entry0=A11,1=A12,2=A21,3=A22.
Accepted inputs: A: -100 to 100 number; B: -100 to 100 number; C: -100 to 100 number; D: -100 to 100 number; Scalar: -100 to 100 number; Entry: choose Row 1, column 1 (0), Row 1, column 2 (1), Row 2, column 1 (2), Row 2, column 2 (3).
How the calculation works
(sA)ij=s Aij
Scalar multiplication multiplies each matrix entry by the same supplied scalar.
Worked example
With a 2 number, b 3 number, c 4 number, d 5 number, scalar 3 number, entry Row 1, column 1, 2×2 matrix scalar product entry is 6 number.
Assumptions and limits
Real 2×2 matrix, one selected entry only; entry0=A11,1=A12,2=A21,3=A22.
