For repeated interpolation calls, the griddedInterpolant is much faster than interp1. However, MATLAB's interp1 used to have an option for faster behavior when the grid was uniform (method '*linear', which now reverts to 'linear'). A simple code for linear interpolation on a uniform 1-D grid can approach an order of magnitude faster than griddedInterpolant.
There are a number of functions on the MATLAB File Exchange to do this, but is there an approach using griddedInterpolant that can achieve faster results?
