im2col function in MATLAB explanation

Let us suppose we have A=[1 1;2 2] 1 1 2 2 ... ok Now img2col syntax == im2col(A,[m n],block_type) Where block type = ('distinct','sliding') distinct places 0's in the final output,,,for padding, sliding,,repeats from the very first matrix element. after all elements read out. Now.. Now [m n] -- very important .... Number of Rows to show = M*N (if m=2 ,, n=2 then each column has 4 elements..) and Number of element fetch to repeat is M in row... That means,, OUTPUT OF THIS - im2col(A,[2 2], 'sliding') ans = 1 2 1 2 -- if A=[1 1 1;2 2 2] A = 1 1 1 2 2 2 then im2col(A,[2 2], 'sliding') ans = contains 4 rows....as 2*2 ... and fetch 2 elements as M=2 here... and slidin...
