[Help-gsl] how to perform 2D convolution of two gsl_matrix

[Abhishek Dutta]

Hi,
I want to perform the 2D convolution of two gsl_matrix (similar to the conv2
method in matlab). Is there a single method to achieve this? Or should I
perform the convolution using the following technique
1. take fft of these two signals
2. multiply the resulting fft
3. take inverse fft

This method would be a good choice as both the matrices (gsl_matrix) have
same dimensions. Is there any other method to achieve this task?

bye
