Hello,
I have 5 columns of normalised snow fall data (between 0 and 1). All 5 column are 9000 rows long.
I want to interpolate this data onto an array of 2984 rows and 6033 columns in size.
Should I use the scatteredInterpolant function to do this?
If so, please help.
Kind regards,

Depends. What to the columns and rows represent?
I'd probably say just use interp1() for each column one at a time.
Attach your table if you need more help.

What does DTM mean? Do you want to consider the table/matrix as an image and look at the gradient within each row (going across columns)?

DTM means digital terrain model.
I want to interpolate the 5x9000 snowfall array onto the 2984x6033 DTM array.
What is easiest way to do it?
Thank you.

Maybe I don't understand. If you have the snowfall in an array, why not simply use imresize()???
snowfall2 = imresize(snowfall1, [2984, 6033]);
