Moving across a table (R2014a)

Hello all.

I have a [101x8] Matrix. I want to interpolate between each column, for which I use a formula. I would like to know how to move across the Matrix after completing the Interpolation between the 1st & 2nd columns ie. how do I tell the Compiler to run the Interpolation between the 2nd & 3rd columns, then the 3rd & 4th columns and so on till the final column is reached. I want to solve this using a Loop. Any suggestions will be greatly appreciated.

Thank you in advance.
