Bug #12356
closedVector covector incorrect multiplication with another vector.
Description
Version 2.2.4
v1 = Vector[2,3,4]
v2 = Vector[4,5,6]
v1.covector.row_size #1
v1.covector.column_size #3
v2.covector.row_size #1
v2.covector.column_size #3
Vector does not have distinction between row and column, there's no column vector notion in the language.
v1 * v2.covector #Matrix[[8,10,12],[12,15,18],[16,20,24]]
Should be illegal. But works like if v2.covector is transposed / column vector which it's clearly not.¶
v1.covector * v2.covector #ExceptionForMatrix::ErrDimensionMismatch: Matrix dimension mismatch
Expected¶
v1 * v2 #ExceptionForMatrix::ErrOperationNotDefined: Operation(*) can't be defined: Vector op Vector
No comments, see my observation below.¶
v1.covector * v2 #Vector[47]
#Again covector treated like transposed / column vector.
Personal observation: Terrible choice to represent Vector like an Array, Vector should be a shortcut to Matrix.
