How can I interpolate a vector to increase the length up to a desired quantity?

Basically my problem is that I have measured with one device and I got different vectors with a specific wavelength and rate (every 3 nm).

My problem begun when I found out that I need to add a correction to the measurements, the correction has the same wavelength but a different rate (every 5 nm). So I need to interpolate so I get the same length for both vectors and ten I can add the correction.

How Can I do the interpolation?

I include the data set in the attachment. The Galad1 is the output data from my device

You can do it with interp1() or griddedInterpolant().
