# convolve(_:rowCount:columnCount:withKernel:kernelRowCount:kernelColumnCount:result:)

Calculates the 2D convolution of a single-precision vector with an arbitrarily sized kernel.

## Declaration

```swift
static func convolve<T, U, V>(_ vector: T, rowCount: Int, columnCount: Int, withKernel kernel: U, kernelRowCount: Int, kernelColumnCount: Int, result: inout V) where T : AccelerateBuffer, U : AccelerateBuffer, V : AccelerateMutableBuffer, T.Element == Float, U.Element == Float, V.Element == Float
```
