MATLAB: Interpolate only between columns

Question

I have a large matrix and I want to interpolate between the columns, i.e. interp2 does exactly what i want EXCEPT i don't want it to interp between the rows.

there must be an easy way to do this!!

thanks!

Answer 1

I think you're looking for interp1, which can be used to interpolate for a number of functions(columns in a matrix) in one pass. To see an example of this, execute the following:

openExample('matlab/InterpolateMultipleSetsofDatainOnePassExample')

If this is interpolating in the wrong dimension, then use the transposition as suggested by J. Webster.
