hello, i have a matrix of size (3 x 4 ) and i need to compare each column with a seperate row respectively.
this may seem confusing but bare with me.
for example.
A= [21 50 60 70
60 70 80 90
27 51 38 35]
B= 19 51 60
C= 20 60 80
D= 80 70 40
E= 50 40 95
RESULT= 51 60 70 95
60 80 80 95
51 60 40 40
so i want to know how to compare the first column in A with row B and second column in A with row C and so on....
baring in mind that when comparing each element, i need the verry next number from rows B C D and E.

We're not so close to be "baring" all, methinks... :)
Clear as mud! :(

So I think calling interp1 on each column using the 'next' method is what you're trying to do.
A= [21 50 60 70; ...
60 70 80 90; ...
27 51 38 35];
B = [19, 51, 60];
interp1(B, B, A(:, 1), 'next', 'extrap')
