Div
One can divide a matrix by a number, but also a number by a matrix or a matrix by a matrix. A matrix divided by a number is done element wise. A number divided by a matrix yields the matrix inverse and a matrix divided by a matrix yields the product of the first matrix times the matrix inverse of the second matrix.
Example M / c
Input
- Example.Quanty
A = Matrix.New({{1,2},{3,4}}) B = A / 2 print(B)
Result
{ { 0.5 , 1 } , { 1.5 , 2 } }
Example c / M
Input
- Example.Quanty
A = Matrix.New({{1,2},{3,4}}) B = 2 / A print(B)
Result
{ { -4 , 2 } , { 3 , -1 } }
and
Input
- Example.Quanty
A = Matrix.New({{1,2},{3,4}}) B = 2 / A print(B * A)
Result

Example M1 / M2
Input
- Example.Quanty
A = Matrix.New({{1,2},{3,4}}) B = Matrix.New({{5,6},{7,8}}) C = B / A print(C)
Result
{ { -1 , 2 } , { -2 , 3 } }
