I asked this question previously also but didnt get a reply !

I have 100 points sin curve and i want to convolve it with 10 point gaussian to regularise my data ! In image processing this is known as gridding algorithm read a paper by JPELT...but i didnt get it how i can implement this image processing algorithm in signal processing.....

Gridding algorithm divides whole image in small grids then this 10 point gaussin convolves with the points in grid....Did any body tried this before

I found this file submitted to matlab central but its too advanced for me right now

I am looking to understand 1st step from paper ! But how this gridding works . My questions are

1. Suppose we have 10 points on Gaussian and 100 points on sin ...so we are convolving 10 points with each point,,,in end we will be getting matrix of 100 by 10,,where each row denotes a convolution for each point of gaussian ....just a question..I always gained useful advice from people here........
