MATLAB: Using interpolation to replace missing values (NaN)

WebJan 27, 2024 · After some experimentation, I found that there is a maximum size of marker that legend will show, which is about 10. Note that the size argument for a line object (i.e. the result of plot) describes the length, while the size argument for scatter describes the area, hence the need to square to get the same visual size. WebThe title of this question is also nearly the answer - Fill in missing values using fillmissing. A = [1 nan 1 2 2 nan nan 3 nan 4 nan nan 5]; B = fillmissing (A,'linear'); This function was introduced in R2016b. The same logic can be implemented using interp1 and isnan. gold coins and a selfish man
