Lookup Table with > 30 dimensions(n-D Lookup Table)

Dear friends,

In generaly, 1 The n-D Lookup Table has maximum n=30 dimensions.

I want to implement 1 n-D Lookup Table has n>30 dimensions. Ex : Lookup table for SINE and COSINE:

Y=SINE(x1,x2,...,x256)

How can I do it?

Many Thanks!

Best regards!

Anyone can help me?

Are you sure that you mean dimensions and not points?

[Ryan G]

What would your inputs be? For example, a lookup table for an aircraft may have inputs of velocity and altitude (2-d) or velocity, altitude and angle of attack (3-d) etc.

I want to implement a SINE function use Lookup table, the input from 0 to 360 and i must have correspond 360 dimensions. How can i do? Thanks!

[Ryan G]

wouldn't this be a 1-d vector where you have one input that represents the input to the sine?

[Jan]

It is very unlikely that you mean 360 dimension. Note that even if you have only 2 points per dimension, you get the huge number of 2^360 elements in the table. You'd need 2.35*10^93 PetaByte to store this and this exceeds the number of protons in the universe.

An array with "3 dimensions" is:

zeros(2,3,4)
