# Problem 319. Biggest Value in the (Neighbor)Hood

For this challenge you get two inputs: a matrix A and an integer value n. Your function should return a Matrix B of the same size as A with integer values. Thereby, the entry B(i,j) counts the occurrence of lower values in the neighborhood A(i-n:i+n,j) (column wise), while symmetric boundary conditions (A(i<1,j) == A(-i+1,j) should be used (compare to padarray('symmetric')). For example,

assume n to be 2 and a matrix A containing double values, e.g.

A =

```    0.3147   -0.4025   -0.3424   -0.3581    0.1557    0.2577    0.2060
0.4058   -0.2215    0.4706   -0.0782   -0.4643    0.2431   -0.4682
-0.3730    0.0469    0.4572    0.4157    0.3491   -0.1078   -0.2231
0.4134    0.4575   -0.0146    0.2922    0.4340    0.1555   -0.4538
0.1324    0.4649    0.3003    0.4595    0.1787   -0.3288   -0.4029```

B =

```     2     1     1     1     3     4     4
3     2     4     2     0     2     0
0     2     3     3     3     1     3
4     2     0     1     4     3     1
2     4     3     4     1     1     3```

Explanation: Consider the value -0.3730 in the first column of A. The two entries above and below are all bigger and thus, the corresponding entry in B is 0. However, the entry 0.4134 is bigger than its neighbors (symmetric boundary condition) and thus, the corresponding entry in B is 4. You can assume that n<=size(A,1)
