The class Mat represents an n-dimensional dense numerical single-channel or multi-channel array.
####Swift Example
```swift
let mat = Mat(rows: 2, cols: 3, type: CvType.CV_8U)
try! mat.put(row: 0, col: 0, data: [2, 3, 4, 4, 5, 6] as [Int8])
print("mat: \(mat.dump())")
```
####Objective-C Example
```objc
Mat* mat = [[Mat alloc] initWithRows:2 cols:3 type: CV_8U];
[m1 put:0 col:0 data:@[@2, @3, @4, @3, @4, @5]];
NSLog(@"mat: %@", [m1 dump]);
```
