@acer 

Thanks again,...  Can you clarify a couple commands please and sorry if this might be elemental stuff.  I understand the convert to list for the column labels and this was probably my first error of why the array text was error'd out trying use the columnlabel option in an earlier attempt.

1.) The original array elements were of a text(string) type, but you use subsindets to "transform" the list elements to string.  I used whattype on the command and see both (array and list) return strings for the elements contained inside.  Why was this necessary other than just using convert to turning the array into a list argument?

    (P.S., I like the u arrow operator vs in-string tools to get the characters after 5th.)

2.)  Can you explain the "transformer" and "rest" arguments as to how you know a valid transformer operator (in this case 'string') and the second argumant option to "feed it" with the u->u[5..]   vs it just acting on the elements?? 

     - I presume a different substring operation could have been used to remove chars 1-4 ? 

Thank you,

Bill

@acer 

Thank You.   Great showing of the command usage to manipulate the axis.  
 

So glad you're a subject matter expert on Maple on this forum.

@acer

Thank you.  You always have the hidden gems of commands.

so much appreciated!

Here is the worksheet

Can I statically post the array3 which is an excel import (ExcelTools) without having to provide the full sheet and the file management commands to get the file data into the array?

I don't think I can post the excel file as is.

Thanks,

Bill

This is a great worksheet and very illuminating of the mode responses.  The animations showing the complex motions is quite amazing.

Thank You,

Bill

Your original email said to contact you to know where best to get these for Windows.  The Git seems to be Unix based mostly (?).

Just a little navigation through your sources and steps to install please.

Bill

@Joe Riel 

Hi Joe and thanks for replying.

I have shied away from emacs or vi(m) as unix based.  My Ubuntu is ver 14.04 and is so old to upgrade its a nightmare on dual boot.   I am about to overhaul the dual boot and remove the Ubuntu in total just to fix windows 10 issues.  It never operated well and spent many hours with the "

sudo apt-get update

process to get past the ancient and new secruity checks that fight each other.

My day job is to use code to do useful things, not chase OS upgrades that obsolete functions or add features never needed, or to close a security holes that broke it in the first place..

PS., Windows does SSDD   ...Sighing much. 

Any assist here would be greatly appreciated and thanks again in advance!

The first time I used this worksheet I used a length command for the vector length and it worked fine. 

Looking back I should have used ArrayTools:-NumElems for the single column vector.  

Anyway here is another try at uploading.Triax_18_inch_arm_X-axis_plane_trimmed_(logic_checked).xlsx

@wswain 

There was an "insert link" button next to the file uploaded.  I can't see it in my message view as posted.  So, here is the native xls file too (if it posts)

@acer 

Thank you for looking at this.  Here is the csv file and I added three columns with the function test "isnumber" to check your idea.  The filter doesn't see any other output except true from what I've seen.

The import matrix line is:

Accel1:=ImportMatrix(cat(path1,"/",Dir_Vect[1], output = matrices)   #returns 141713 x 5 Matrix

Accel2:=(Accel1, 3)   #To select column 3 for processing  

Accel3:=(Accel2, 3000..len1_int)   #trims the channel's idle wait data off the beginning until 1 second before real data is live until the integer length of a selected segment

Thanks,

Bill

@acer 

my my main thought was that we have quite a few users on Matlab and if there is a benefit to “port” across the commands for readability, etc.

I am not interested in making Maple into MAtlab lite.

Appreciate your responses

@acer 

This is my first use of maple eigenvalue functions of the linearAlgebra package.

I was looking at the outputs of the eigenvalue function and got my values expected, although not neatly sorted lowest to highest as the matlab eig(Matrix) returns.   The sort function worked great on the eigenvalue vector to order them.

I assumed the eigenvector returned the matrix of vectors, but not the values as they are two unique commands.

When you say MTM is part of the regular package do you mean loaded using with(MTM) call.   As to getting an external toolbox?

I still ask is there any benefit to the MTM functions over Maple?   Or, Maple direct is better as not trying to replicate Matlab?   

I have no druthers with Maple over Matlab.  I do have issues that a lot of reference books use MATLAB and the function mapping to Maple is sometimes a challenge to replicate results if not using the commands in the same way.

Thanks in Advance and for your first reply.

fixed the errors and works like champ.  I love it when things works as advertised.

[x(t)] was the correct list syntax AND returntype is Datapoint - NOT- Datapoints

I do wish the error checker was a little better correcting and explaining syntax errors.

@Joe Riel 

thank you.  I abbreviated the imports for brevity, but the rest of the comments are great.  Will try shortly.
