How to calculate size of 2d vector

Web9 jan. 2024 · int row_numbers = sizeof(A)/sizeof(A[0]); For example: int A [3] [4]; The size of memory consumed by the array A will be 3 (rows) x 4 (column) x 4 (size of int) = 48 bytes i.e sizeof (A) shall return 48 bytes. Also, sizeof (A [0]) in the example will return 4 (number of elements in a row) x 4 (size of int) = 16 bytes. Web5 sep. 2024 · In this tutorial, we looked at different ways to calculate vector lengths or magnitudes, called the vector norms. Specifically, we learned how to: calculate the L1 norm which is calculated as the sum of the absolute values of the vector. calculate the L2 norm that is calculated as the square root of the sum of the squared vector values.
