Using colon operator to create evenly spaced vectors for individual elements of arrays simply and without looping

Is there any way (other than using looping) to perform an element-by-element operation on two matrices such that a vector is created with equal spacing between the corresponding elements of each matrix? For example, if I had two matrices:

A=[1,2,3; 4,5,6] B=[12,13,14; 15,16,17]

It there a simple way to create an array (perhaps a cell or multidimensional array) that holds A(1,1):B(1,1), A(1,2):B(1,2) and so on, without manually typing all of this?

Apologies in advance if the question is unclear or the answer is obvious--I have minimal matlab experience and have run into a mental block trying to get this to work.

A=[1,2,3; 4,5,6];
B=[12,13,14; 15,16,17]

C = cellfun(@(x,y)x:y,num2cell(A),num2cell(B),'uni',false)

No guarantees it'll be faster than a for-loop though. The conversions using num2cell() aren't known for their speed.

Thanks! I'll give it a try. It actually works out, as the situation in which I'll be applying this involves cell arrays already. Apologies--I probably should have mentioned that rather than just going for simplicity in my example. =P

No! Simplicity in your example first - Good job! (+1)
