title: How to convolve 2d signal with a 1D kernel without using loops in matlab?
body: <p>I have an image.  I want to convolve it.  I have different type of kernels for both x and y directions. In the function <code>con(u, v)</code> we can only specify one vector and we have to use loops. For <code>conv2(A, B)</code> we have to specify a composite kernel.  I want to approximate 2d convolution with a series of 1D convolutions.</p>
