i have a matrix i.e image size is 435*262 (y=435*262) i want to convolve with a 1d array i.e a=[0 1 0] z=conv2(double(y),double(a));% code for convolution my question is can i convolve in this way is it right or should i have to convert 'y' in to 1D or i have to make 'a' in to 2D i am little bit confuse can any one help or provide me the code if m writing in wrong way

Yes, you can convolve in that way. a is already 2d, it just happens to have dimensionality of 1 in one of the directions. You have to make sure you get the right orientation though of course for the direction you want to convolve. Although with your filter it doesn't matter anyway since it doesn't do anything!
