hello,
I want to calculate the difference b/w different elements of a matrix corresponging to any single element.
say, i am having any 3*4 matrix and want to calculate the difference from element [1 3] with each and every remaining lemnents of the of the matrix.

say this is the matrix A = [ a b c d; f g h i; j k l m ]
and if i want to calculate the difference from element a11 with respect to each and every remaining element of the matrix using a loop because i will have to do the same for a matrix with larger dimensions.

A = rand(3,4) ;
iwant = A(1,3)-A(:)

Thank you for kind response sir but i have the different query.
say this is the matrix A = [ a b c d; f g h i; j k l m ]
and if i want to calculate the difference from element a11 with respect to each and every remaining element of the matrix using a loop because i will have to do the same for a matrix with larger dimensions.
