How to substract every two adjacent column from a matrix

Hi,I new to matlab and i couldn't solve this issued. I have a matrix of [3750,666] and I need to subract every two adjacent column and normalize it. Can somebody help me with this?

i have a matrix x with MxN = (3750X666) and i want to subract every two adjacent column x(:,3:N)-x(:,1:N-2)) and create a new matrix with the same dimension, how can i do it?

i want to subract every two adjacent column x(:,3:N)-x(:,1:N-2))

Are you asking here for a different computation than the one you originally posted? If not, un-Accept the answer and explain in what way the answer doesn't accomplish what you're after.

Perhaps this is what you were looking for,

y = conv2(x,[1,0,-1],'same')./x;
