I want to plot a 2D fig by maple. my data are in an excel file and they are too much to import them one by one manually. When I copy and paste them in maple, they appear in a column...

thank a lot for your help.

## Find Trendline and R-squard value from data...

Hi

I have some data:

Matrix(10, 2, {(1, 1) = 0, (1, 2) = 0, (2, 1) = .5, (2, 2) = 3.25, (3, 1) = 1.0, (3, 2) = 5.82, (4, 1) = 1.5, (4, 2) = 7.50, (5, 1) = 2.0, (5, 2) = 8.79, (6, 1) = 2.5, (6, 2) = 9.83, (7, 1) = 3.0, (7, 2) = 10.66, (8, 1) = 3.5, (8, 2) = 11.35, (9, 1) = 4.0, (9, 2) = 11.94, (10, 1) = 4.5, (10, 2) = 12.46})

I want Maple to make a trendline fitting a Logarithmic function. I can make it output some function with this:

LeastSquares(`<,>`(.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5), `<,>`(3.25, 5.82, 7.50, 8.79, 9.83, 10.66, 11.35, 11.94, 12.46), x, curve = a+b*ln(x))

It outputs:

5.96497783539274+4.25309474196387*ln(x)

But please notice, the dataset in the function does not have the first 0 and 0. If i do that:

LeastSquares(`<,>`(0, .5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5), `<,>`(0, 3.25, 5.82, 7.50, 8.79, 9.83, 10.66, 11.35, 11.94, 12.46), x, curve = a+b*ln(x))

It outputs:

Error, (in Matrix) numeric exception: division by zero

Besides that, i need the R-squard value for determinating how well it fits.

If i do the same thing i Excel the data set will give a formular: 5.5464ln(x)-0.2175 with a R-sward value of 0.9985.

How can i do this i maple?

## Will Matrix Browser export data to specific destin...

My attempt to export array data using the Browse>Export option when looking at the data fails to work as needed.

The exported data always start in cell A1 of the Excel worksheet even a different starting cell is entered into the Matrix Browser export window.

In summary, my experience is that the Matrix Browser matrix export in Maple 16 and Maple 17 ignores the information about the intended starting destination cell in the Excel file.

Does anyone find that the Matrix Browser exports to a starting Microsoft Excel cell other than A1?

This exporting with Matrix Browser worked find in Maple 15.  It has been broken in Maple 16 and 17, including Maple 17.02.

Thanks.

I was successful in getting the Maple add-in to load into Excel 2013 but the help file accessed in the Add-In Ribbon is not found.  Does anyone know where in Excel that file can be loaded?

## Excel 2007-2010-2013 integration with Maple 17...

Hello, everyone!

Last week I’ve encountered problems with integration of Maple 17 in Microsoft Office Excel 2013. The Maplesoft note on the point (http://www.maplesoft.com/support/faqs/detail.aspx?sid=32651) offers some ways of fixing it up, though I’ve run all of them the problem is the same:

While the connection is established, after entering the formula “=Maple(“x+x”)”, the Excel returns “Critical Error in Formula”

Before contacting the Maplesoft Technical Support, I want to ask here whether someone had the same case and managed to solve it.

## Export data calculated in a for loop...

Hello,

it is more or less my first time using maple for my research. During my mesurements I collect data and store those in an excel sheet. The I made calculations row by row.

I figured out how to import the excel sheet and calculate row by row. Maple calculates the correct results, but how can I easily store the results again, for example row by row in an excel sheet or csv?

This is my code:

> restart;#Range of the Matrix A1:KXXXXprint(??);

## When can Maple support for Excel 2010...

## Problems with Excel import...

Hey guys,

I do have a problem with Excel Import.

What I wanna do is import 2 collumns from a Excel-File.

The first Column are the X-coordinates and in the second column are the y-coordinates.

After the import of the two columns (each with around 1000 rows) I would like to run a formula for each of this x/y pairs. Means for example a formula i1:=2*x+y or something like this.

And I would like to get the results also in a...

## How to "save" data imported from an Excel file...

Dear Maple users

I am working on importing data from an Excel-file "Data.xlsx" into Maple. This is done using the following commands:

> restart;
> with(ExcelTools);
> X := Import("Data.xlsx", 1, "A3:A63");

One strange behavior is the fact that I receive an error message: Error, (in ExcelTools:-Import) Could not open the file.

When I close the Maple file and open it again and reexecute, the error disappers and everything works....
