Find the Norm [[-3,0,-6],[-2,3,4]]

Problem

‖[−3,0,−6],[−2,3,4]‖F

Solution

1. Identify the type of norm to be calculated. For a matrix, the default norm (unless specified otherwise) is the Frobenius norm, which is the square root of the sum of the squares of all its elements.

2. Square each individual element of the matrix.

(−3)2=9

(0)2=0

(−6)2=36

(−2)2=4

(3)2=9

(4)2=16

3. Sum all the squared values together.

9+0+36+4+9+16=74

4. Take the square root of the resulting sum to find the Frobenius norm.

√(,74)

Final Answer

‖[−3,0,−6],[−2,3,4]‖F=√(,74)
