Hello
I am after a vector/matrix/cell style object like there is in Matlab whereby we can read data into this matrix and maipulate it. All the sizing etc is automatically accounted for by the object itself when the data is assigned to the object, and its easy to do things like pull out columns 1--5, count etc etc. Converting from an existing Matlab program and Matlab has lots of nice features for manipulating cells/vectors/matricies which I would love to have avaiable. Contents is not just numbers so its not a math vector etc I am after. For example it might read in a table of data where some fields are text and some are numbers. Basic manipulation, for example append, combine, remove these cols, remove these rows, sort, remove repeats, unique etc etc. Regards A |

The only thing like Matlab in Excel is Matlab itself. That is,
Mathworks sells an Excel add-in that uses Matlab for all the computations. I think its pretty spendy though. Really, the closest built-in object with the capabilities that you're describing is probably a worksheet. Excel has a few built-in matrix functions, but with nowhere near Matlab's capabilities. You'd have to code a lot of it yourself. |

Hi. Excel can't do these operations as well as a dedicated math program.
If you would like, here are some ideas that may help a little. Good luck. :) ... things like pull out columns 1--5, count etc etc. Sub Demo() Dim v, c Const All As Long = 0 '// 2 Dim array from A1:C5 v = [A1:C5] With WorksheetFunction '// Extract all rows in the 2nd Column... c = .Transpose(.Index(v, All, 2)) '// How many elements? Debug.Print "Number of items:"; Debug.Print (UBound(v, 1) - LBound(v, 1) + 1) * (UBound(v, 2) - LBound(v, 2) + 1) '// Simulate "AppendTo" '// Add a new row (simulate adding a new list item) v = .Transpose(v) ReDim Preserve v(1 To UBound(v, 1), 1 To UBound(v, 2) + 1) v = .Transpose(v) v(UBound(v, 1), 1) = "a" v(UBound(v, 1), 2) = "new" v(UBound(v, 1), 3) = "row" End With End Sub HTH: -- Dana DeLouis Win XP & Office 2003 "A C" wrote in message ...

In excel, that would be a spreadsheet.

Thanks. Do you have an examples/demos of it working (programming skills not
great yet) so I can see how you declared things and how you called them. Can it handle data that has multiple types? eg strings in some cells and numbers in others all within the same range? That said maybe I can just assume they are all strings, im not really wanting to do any calcs with the contents just reformatting and outputting etc. Regards A "Alan Beban" wrote in message ...
