Hi, I couldn't draw two dimensional convolution which is conv(rect(x),rect(y)). I want to see the 3 dimensional plot. I tried by ezplot and mesh but it says for computing 2 dimensional convolution, the arguments should be in vectors. thanks for your response. warm regards, pouya

For 2-Dimensional convolution matrix you can use the function 'conv2'.

'ezplot3' can be used to plot in 3D.

Please refer to the following documentation links

conv2

ezplot3

thanks for your response. my problem is that i don't know how to construct the matrix for conv2(rect(x),rect(y)) and then if i know this i am able to use mesh, ezplot3,... to plot it.
