Interpolating Irregularly Spaced Data
显示 更早的评论
Hi,
I have many sets of data, all are 2D arrays, where the first column is a depth and the second column is a reading taken at that corresponding. My problem is that I would like to interpolate the data so I have a grid of readings (col 2) for increments of 0.1 depth (col 1). The depth data in col 1 is irregularly sampled and is not the same for each set of readings I have taken. Linear interpolation would be preferable.
Any Help would be greatly appreciated,
Tom

Use interp1 function:
interp1(col1,col2,col1(1):.1:col1(end))
