Hello there,
I have a data consisted of two column, let's say the first column is depth and the next one is data_x (see excel file attached). The y (depth) has irregular spacing (see fig). My intention is how to make an interpolated profile with a regulation as follow (see fig):
  • the first upper 10 depth should be interpolated with 1-depth point resolution
  • the next one (12-30) depth should be interpolated with 2-depth points resolution
  • the next one (>30) depth should be interpolated with 50-depth points resolution
Anyone knows how to do that?

newy=[1:10,12:2:30, 50:50:500];
newdata=interp1(y,data,newy);
