Matlab 2D Convolution Kernel

Matlab 2D Convolution Kernel. I want to implement 2d kernel convolution of a signal in matlab. That's a convolution on a 2d signal only being applied to 1 dimension.

I need to estimate a 5 x 5 convolution kernel to fit ( linear data fitting) a complex matrix of size, say 128 x 512 to another matrix of. That's a convolution on a 2d signal only being applied to 1 dimension. If we assume that the variable k is used to access the rows and t is used to access the columns, you can.

The input to the function is the 2d kernel and dimensions of the image to apply the convolution upon and the shape of the convolution ('full', 'same', 'valid' as in 'conv2 ()'). I need to estimate a 5 x 5 convolution kernel to fit ( linear data fitting) a complex matrix of size, say 128 x 512 to another matrix of.

Well in 1d, it means, for example that the convolution of causal signals will also be causal. The reason that your 1d convolutions combine to give you the same results as the 2d convolution is that your filter is separable.
