MATHEMATICS MATRIX CALCULUS THEORY
QUESTIONS AND ANSWERS,A+ GURANTEED.
1
Q
Determining a minor in a matrix
A
Remove the elements in the target’s row and column, including the target itself
Calculate the determinant of the new matrix
2
Q
Matrix determinant
A
Only applies to a square matrix
Difference ‘meaning subtracting’ of the individual products of the numbers listed diagonally from the
top-left corner. When you run out of space, go to the next row and start at the first column
3
Q
Starting position in a matrix
i=1, j=1
A
Start in the upper-left (like reading a book)
4
Q
Dimensions of a matrix, and propper notation for element identity
A
Rows-by-columns
, 5
Q
Referring to an individual item in a matrix
A
(Matrix-symbol-title)ij
Where i is rows from top and j is columns from left
6
Q
Matrix addition/subtraction
A
Add/subtract each element to the element of that position within the other matrix
7
Q
Scalar multiplication of matrices
A
Multiply each element within the matrix by the scalar-constant
8
Q
Transposing matrices
A
Row 1 items fill column 1 of the new matrix and so on for each row
Writen as [matrix]^T
9
Q
Size of a product matrix in Matrix Multiplication
