hi,

i'm looking for a method or an object, that makes ist possible to interpolate or extrapolate values between arrays of different sizes.

an example: i have an array of size 128 filled with data and i want to interpolate (strecth) the data information into an array of size of 2048.

does anyone have an idea about that?

best regards,

matthias

Use [tabread4], which uses 4-point interpolation, to read the 128-point array and write those values to the 2048-point array. Something like this should work:

[2048(
|
[until]
|
[f 0]X[+ 1]
|\
| \
|
|
[/ 16]
|
[tabread4 128-point]
|
| [r index]
| |
[tabwrite 2048-point]

thanks a lot. it worked!
