### Implement imfilter(matlab) with OpenCV

Hello,

I am trying to port matlab code to c++ with opencv. I could import most source code but I had serious problems with the imfilter function. I was trying to use the filter2d function for c++, but It doesn't get same results between among themselves. What is the difference? How I could get the same result? The source code is very simple.....

```
//src_gray has one channel
//C++ code
filter2D(src_gray, dst,-1, kernel);
//Matlab code
dst = imfilter(src_gray,kernel)
```

Inputs:
src_gray=

```
11 11 11 11 11
11 11 11 11 11
```

kernel =

```
2 2
2 2
```

output:

Matlab:

ans =

```
88 88 88 88 44
44 44 44 44 22
```

C++:
[88 88 88 88 88;
88 88 88 88 88]

My c++ code:

```
/// Initialize arguments for the filter
Point anchor( -1, -1 );
double delta = 0;
int ddepth = -1;
Mat dst;
float data[2][5] = {{11,11,11,11,11},{11,11,11,11,11}};
float kernel[2][2] = {{2,2},{2,2}};
Mat src = Mat(2, 5, CV_32FC1, &data);
Mat ker = Mat(2, 2, CV_32FC1, &kernel);
filter2D(src, dst, ddepth , ker,anchor);
cout << dst << endl;

char c;
scanf("%c",&c);
