Hi, I have an excel sheet with sediment data ~1500 rows, each row is comprised of various data such as station id, lat, long, particle diameter etc. There are about 75 different stations and about 20 samples from each station. I am looking to calculate the average diameter in matlab of each station based on it's station id #. Thanks for the help.

It should be a simple matter of calculating the mean at that point. Wayne

When you say: "> I have an excel sheet with sediment data ~1500 rows, each row is comprised of various data such as station id, lat, long, particle diameter etc." Are you saying that each row is one kind of data, e.g. station id, or in each row do you have multiple measurements of different data, e.g. station id, lat, long, etc. You can also do File -> Import Data and Matlab will basically walk you through importing the data, including creating a variable based on a row or column header.

Matlab will have cleverly put it into column 6 in a. So to get the mean, you would say mean(a(:,6))

I'm not looking to take the mean of all of the data but just of a single ID number which is only about 20 rows in a 1500 row work sheet. I need to do this for ~75 different ID numbers.

I need to move an Excel Worksheet to a different Workbook with matlab. I am currently able to create an Excel worksheet and add data to the required cells. I want to be able to move this Worksheet to a different workbook. When I try the code, >> invoke(Activesheet.Move,'Resutls.xls') it creates a new workbook and moves the worksheet to the newly created workbook instead of 'Resutls.xls'. It also gives the error ??? One or more output arguments not assigned during call to "Move". Does anyone have any ideas? Thanks, Jared <http://www.420megs.com/users/e...

Hi guys, I have a small query regarding Excel worksheets. I have a spreadsheet with around 20 worksheets in it. Do any of you know of the easiest way to import it into Matlab?

Hello, Is there any limitation to run Matlab from Matlab, as a system command, on Linux platforms ? I tried to start Matlab, both using the ! syntax (!matlab&) or the system command (system('matlab&')), the Matlab splash screen appears, but the new Matlab session closes rapidly . When I do the same with a script of mine (system('matlab -r "myscript"&')), my script is being executed, but Matlab finally crashes . If I remove the &, it works well, but the first Matlab session is blocked till I close the second one . I run Matlab on a Linux 64bits pla...

Hi, I was working with the Matlab builder magic square example (can be found in matlab builder users guide) in Matlab to compile and build m-files into COM objects for Excel. Essentially, the building process creates a .bas file which can be imported into Visual Basic Editor in MS Excel. In the VB code, the Matlab functions essentially end up being wrapped up inside COM objects and you can invoke these functions in the excel spreadsheet. The example works successfully for output to a single cell. For outputing to multiple cells simultaneously, the code changes a little as a macros are in...

Hi, I am trying to delete some worksheets in an Excel workbook. These excel worksheets have data as well as some pictures. I just want to delete the non-empty excel sheets before running a long code. These sheets have data from the previous execution of the same MATLAB programme. I looked at several messages posted on the web, but none of them discuss about deleting non-empty worksheets. I would be grateful if you can help. I am using actxserver for accessing the Excel application. Many thanks in advance, Dilbag ...

I want to write a matlab code that will work behind excel. Basically, the users will enter input to an excel sheet, click a button on the secreen and this will trigger a matlab code that comes with the excel sheet. The code will run and give the output on an excel sheet. The users don't necessarily have matlab. They should be able to run the code though. Is there a quick and easy way to combine my matlab code with an excel sheet? thanks, onur. ps. I am familiar with vbasic. However, I prefer to include a matlab code since it runs faster with vectors.

Hello everyone, How do I compile MATLAB M files into a form that can then be called from within the MATLAB interpreter?

I have the MATLAB compiler, so I just need to know what to do with it to get this to work.
