This function replaces NaN values in a 1D array with interpolated or neighboring values. Interpolation schemes assume data are evenly spaced. This function does not extrapolate.
Syntax
x = repnan(x);
x = repnan(x,method);
Description
x = repnan(x) returns x sans NaNs.
x = repnan(x,method) specifies a method for replacing the original x's NaNs. Methods can be
'linear' (default) performs linear interpolation over missing values in x,
'nearest' performs nearest-neighbor interpolation,
'spline' performs spline interpolation using not-a-knot end conditions,
'pchip' is shape-preserving piecewise cubic interpolation,
'cubic' same as 'pchip',
'v5cubic' cubic convolution via Matlab v5 algorithm
'next' replaces NaN values in x with the next non-NaN value in x,
'previous' replaces NaN values in x with the previous non-NaN value in x,
