comment Plot showing discontinuity where it shouldn't
@Artes ok that worked. Thanks! Do you have a sense of why I am getting an Intermediate when I differentiate?

@Mr.Wizard no but I suppose I could always sort it on the first column.

comment Export to Excel gives error for large lists
Thanks a lot for your answer. Do you have a sense of why this is working for *.xls but not for *.xlsx ?

comment Exporting data to a new excel sheet of a pre-existing excel file
@SjoerdC.deVries I spent a bit of time trying to mimic the .NET but I couldn't get it to work. Thanks for linking to it. I'm not very far from getting it. Whatever I am doing, does open the right excel file but as of now closes it right back. I'll look at it again in a few months when I have more time. Right now I have just switched to saving data as "*.dat" Thanks :)

comment saving Manipulate data inside a notebook
@MarkMcClure Thanks a lot for your answer. I used the SaveDefinitions right now and picked it as the accepted answer because that seemed simpler but I will now try your cell initialization method. I'm sorry, I can't believe that it has taken me 8 days to respond. Thanks a lot.

comment saving Manipulate data inside a notebook
@Sjoerd C. de Vries and Mark McClure. Thanks for both your answers. Since I had to accept one, I went with Sjoreds. Right now I am using SaveDefinitions but when I have to make an important presentation, I will not take a chance and use Initialization.

comment Function to select a row whose kth element is closest to a given number
I just looked up memoization on wikipedia. It will take be a bit to appreciate and understand the differences between the two ways you described. To address your comment, I actually have a list of 20 different numbers each for about a 100 Matrices. So b , the comparison number, is itself a list and for each of those b's I want to find something in column k closest to it. Then I do this for a 100 Matrices, each with a unique b. This is for one set of overall parameters. So I might wind up doing 2000 such uses of the function, many many times.
