@Carl Love as u are saying am doing same but whenever i enter command of ImportData() and after selecting file it ask me for format of file. If am not going for select file format option my maple stops it give me error and when i go for select file format option it directly gives me ImportMatrix option as u have seen in worksheet. Am using maple 13 so am not able to get it. worried alot

wel for the crank nicolson am attaching worksheet u can see from it. crank_niclosn.mw 
by changing value of t and fixing m and n at 20 i got above table 1. so now i think may be it will help you
 

and for cubic spline table worksheet is cubic_spline.mw same here fixing m and n at 20 and changing t i got table2 
and in worksheet you can see output U₁₉ i just considered U₁₉ in my table.
