Hi if i have matrix (6 by 4) like the following:
11 1 1
12 4 3
13 3 3
14 2 3
15 4 7
16 3 4
I need to make up the missing values of different columns by the previous value of the respective columns. missing values in the first value of a column will be replaced by the next immediate available value. Can any one please help me by showing the MATLAB code to do this? This will be much appreciated.

Not sure which elements are missing since HTML for some reason compresses all multiple spaces into one space. How about interp()?
