Question

Suppose i have a 2-dim array of 512*512 elements. how i can access pair of element in row wise by matlab or c.

Answer 1

K = rand(512,512) ;  % a random 2D data

You can access a row by: picking first row:

K(1,:)

10 th row:

K(10,:)

nth row:

K(n,:)

YOu can pick a column by:

First column:

K(:,1)

77th column:

K(:,77)

nth column:

k(:,n)

You can pick (i,j) element using

K(i,j)
