I have a data set of distance, speed and acceleration and I'm looking for a method to interpolate the data and get a new interpolated variable of distance - speed and another one for distance - acceleration. The issue is that I want the interrpoldation to be exactly at each 1 meter (i.e. 1m, 2m, 3m, 4m ......) also the data is arranged in ascending order but not fixed slope so i can't say interpolate after each 10th value. my question is how can I interpolate the data with respect to distance at each 1 meter in other words how to ask the matlab to interpolate the distance with speed when the distance reached 1 meter and take the distance exactly after or before the first time he reached 1 meter (i.e. in case of having 0.9 - 1.2- 1.5, thus it should take 1.2 and (0.9 or 1.5))
