Hi I have a 2d matrix of integers, representing a digital elevation model of a glacier. I need to smooth it - interpolate between cells, but I can't find a way to do so. Thank you

Starting in R2023b, you can smooth noisy data in two dimensions by using the smoothdata2 function. As of R2023b, the supported smoothing methods for smoothing in two dimensions are average, median, Gaussian-weighted average, linear regression, quadratic regression, and Savitzky-Golay filter.
