Interpolating Arrays to be Same Size

I've got two arrays that will change size depending on the dataset that I'm feeding into my script. For the purposes of this question, let's say I have iP_Axial setup as a double format array having size 230174x1, and dP_Axial setup as a double format array having size 59503x1. For comparison between the two arrays later in my script, I need both arrays to be the same size.

I believe I need to interpolate the dP_Axial array to force it to the same size as iP_Axial, but I can't wrap my head around the best way to do so. Can I ask for tips and guidance on doing this?

interp1(dP,linspace(1,numel(dP),numel(iP)))
