What is lookuptable equivalent when the break points are also matrices?

Hi,

I have three matrices let's say A,B,C each of order mxn. I want to find corresponding value in C if inputs are A and B.

For example:

inputs: A(1,1), B(1,1)

Output: C(1,1)

No only this, I should also be able to find corresponding interpolated value in C if A and B inputs are interpolated values within their respective matrices.

2d lookup table is an option, but the problem is my breakpoints are matrices.

Thank you.

It is not clear what you mean by "breakpoints", a word which already has a specific meaning:

Hi,

Maybe the title is not apt, but please read the problem which I have explained.

Thank you.

@manoj saladi: are the values in matrices A and B strictly montonically increasing along the two dimensions of the matrices?

[manoj saladi]

B matrix is montonicaly increasing where each column has same value. A matrix is not monotonically increasing, each row has a constant value until certain column number and later starts to decrease.

"... if A and B inputs are interpolated values within their respective matrices"

Are the inputs values or indices?
