@acer , thank you for your reply and the file. Unfortunately it does not completely solve my problem. The export of the measuring device does not give an extension to the exported file, so my question is mainly can I import the file without manually adding .txt? If I try to do that now, Maple states null file and refuses to import the file.

Thank you for your help!

@dharr thank you for taking time to reply. Yes you are right but at that time I had only a few files so I changed the extension manually to .txt. Unfortunately, the export of the measuring device does not give an extension to the exported file, so my question is mainly can I import the file without manually adding .txt? If I try to do that now, Maple states null file and refuses to import the file.

If you find it more suitable to ask my question in the old treat, I will try to do that in the future.

Thank you for help.

@rlopez thank you for your help and clarifications. I have been able to solve, with the help of some power user, now my problem. Thank you for your continuous support to this forum.

@acer I know Maple is extremely powerful so I would like to ask you whether there are other methods than the one you showed, to achieve the same result? Thanks again for your help.

@acer thank you so much for your assistance. I do apologize for rephrasing my question but I did not know how to delete my previous (unclear) question. 

@Axel Vogt You are probably right but how can I solve than my equation? How would you do it? Below I give the syntax in Mathcad:

Thank you for your help!

@rlopez I am making a transition from Mathcad towards Maple and the formulas used in the worksheets above work as they should in Mathcad. Of course syntax is different in Mathcad. As such I believe my problem is related to using the wrong syntax in Maple. Any help in that respect would be more than appreciated.

@rlopez thank you for your swift reply. But could you help me to solve the attached file element wise? The file with single input works fine but the one with multiple input does not.Single_Input.mw         Multiple_input.mw   Thank you in advance.

@dharr thank you for your input.

@mmcdara forgive me my ignorance but what is a terminal window? 

@mmcdara Could it be that the "sed" command does not exist in Windows but solely in LINUX?

@mmcdara and @tomleslie thank you both for your help. I will need some time to play with the solutions to fully understand your approach. @tomleslie I fully agree with your comments on the format but it is not me that created that format but the device we use for the measurements and unfortunately we cannot change the format. I also would like to express my gratitude for all the efforts both of you make on a daily basis to help people out! From my side this very much appreciated. Have a nice weekend

@Carl Love thank you for this additional clarification. I wish you a pleasant weekend.

@tomleslie thank you for your clear explanation. I wish you a pleasant weekend

@tomleslie thank you for your guidance. In general what would you use instead of vectors? In my former software this was the most convenient but probably not in Maple. I will take a closer look to your approach later on.
