Matrix Equality Check

Problem

Return True if matrices A and B have the same shape and all corresponding entries differ by at most 1e-9.

Otherwise return False.

Hint

Shape mismatch is an immediate False; otherwise compare entrywise with a tolerance.

in: [[[1,2],[3,4]],[[1,2],[3,4]]]

case 2

in: [[[1,2],[3,4]],[[1,2],[3,5]]]

expected: false

case 3

in: [[[1,2]],[[1,2],[3,4]]]

expected: false

case 4

in: [[[0.30000000000000004]],[[0.3]]]
