This question is about the Basismatrix in the context of Linear Programming. Basically (haha!) we have the Matrix of the standard (or normal) form, which consists of (A|E) with the coefficient matrix ...
I'm trying to say set A is the set of nonnegative integers that not of this two forms $3x^2 + (6y-4)x - y\ $ and $\ 3x^2 + (6y-2)x + (y - 1)$, for example: $4=3 \cdot1^2+(6 \cdot1-4) \cdot 1-1\ $ is ...
I'm trying to concatenate a rotation matrix with a 4x4 homogeneous transformation matrix with column-major convention. I want this rotation matrix to perform a rotation about the X axis (or YZ plane) ...
Is there any convention of the order of operations in a term with both ordinary matrix multiplication and hadamard (elementwise) multiplication? Obviously, $$ A ( b \circ c ) \ne (A b) \circ c $$ ...
Is there a convention to write the all ones matrix in formulas? I'm going to write about the following formular: $$ A = B + XD + DX + N $$ Where D is a diagonal matrix and X the all ones matrix: $$ ...
Will the terms complex and imaginary ever be replaced? At least within beginning classes? I imagine it is more of a kind of hazing into the "mathemitician's club" to allow the terms to confuse ...
