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

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.

@tomleslie    I do try to dig through help before coming here.

I can see I have not worked much with the Maple matrix operators and this is just more familiariztion with the op command and the other nuiances.   

The approaches have been very helpful to put me back on track.

Regards,

Bill

@dharr   would most Maple users that understand all the maple uniqueness considered heavy users on a daily basis?   As an engineer I am not a professional coder, but need to use the tool (any tool, Matlab, MathCAD, fortran of old, etc.) to solve problems.   Maybe this is all easy(?) for professional code writers.  How unique are these language constructs to other programming languages?

I use Maple for my Professional License continuing education needs as I believe the tool is the more robust but it has its code operations features that seem a bit difficult.  JMHO.

Thank you and will continue to press forward with this and the info above.  Appreciate any continued dialog.

Bill

@tomleslie    Thank You very much!

Looks like pretty much the goal.  I like your method of changing the '-', "&ndash"

This is my lack of maple experience and limited usage of -> arrow operator and the ~ tilde operator in next line.   I'll check in the morning in slow time.  any hints would be helpful.

Next the output matrix is great, my goal will be to reduce the 166 columns as a lot of that data is not necessarry.  But for ease at this moment I like the approach and if small memory footprint, just carry the excess data along.   

Just reading through how you extracted and if you could comment around the seq function on what it is doing within "Matrix".   I don't see the from 1 to end (or last row) as the seq idx.  Is the 1st argument the matrix  SD[1st row, all columns] being set to start scan as start row?

I see/note the scan=columns (read across columbs in a row?) at the end.   

the NULL line is confusing 

lastly forgive my newness with the op command.  In this case op[1,1] is referencing which expression that its grabbing the [1st operand of expression 1(?)] .  Is it the 1st row as expression 1?

Back on memory.  Did you check the import time and can the var SD be checked for memory utilization?  Presuming this grabs a copy of the full table.  I am not sure how some 10,000 record data sets will import though like this on performance.  I did look at the matlab xlsread as the goal I was trying with Maple (the hard ay) to scan in place the data without loading into mem as a var.

Regards,

Bill
