Given an input array of strings (characters) s, pick out the second column of data and convert it into a column vector of data. missing data will be indicated by the number . if you encounter missing data, you should set it to the average of the immediately neighboring values. (this is a bit simpler than using `interp1`.)
if the input array is s = [ 'a' '0096' ; 'b' '0114' ; 'c' '' ; 'd' '0105' ; 'e' '0112' ]; then the output variable `t` is the following column vector. t = [96 114 109.5 105 112]';
compose a function read_and_interp which accepts an array in the above format and returns the data converted as specified. you may find the conversion function `str2num` to be useful.
