Hi everyone If a have a nested matrix like this one below and I want to exclude the first row  of each small matrix in the original one How can I do that , when I try (submatrix function) it excludes the first matrix , but I want to exclude the first row of each matrix by the way my ORIGIN =1 I'm expecting the answer to be like (X sub ) in the second picture Thanks Yusra  

Hi thereI have a problem with this function . The issue is R is a cumulative value so the R2=R0+R1> R3= R0+R1+R2 and so on... I wanted to implement that in this function but an error ( must be a vector ) shows Is there a way to fix this or to write it differently Thanks The sheet is attached prime 11 

Hello, I'm trying to generate a 3D curve from a table or matrix of (X, Y) values along with a vector Z, which contains one value for each (X, Y) pair with Mathcad 11.0.I tried using createmesh, but without success. Do you have any suggestions on how to achieve this? Thank you for your help. Update : Added Excel file to import the matrix.Update : Link to the mathcad file Emilien

Hi,I am having few issue with plotting transfer function:Bode plotHow to make line more obvious in the low frequency area?How to get ride of #4 zone of the plot, it doesn't have anyI cannot plot phase plot, and i don't know why, please.Attached is what i have done.

We often deal with mathcad calculations that are 100 pages or more.  These can be unwieldly to navigate and check especially for those that did not develop the mathcad calculations.  One thing that could greatly improve the formating of mathcad would be to have the ability to have something like the tabs in an excel sheet.  Another way to do this would be to have the ability to have chapters or sections that could be tabbed through.  If it was done with chapters or sections, there could be a table of contents page with links to each section.  I know that mathcad had the ability to hide calculation regions but this is not nearly as user friendly.  This is a wish list item that I think would really improve the user interface for many users.  

Hi! I tried to find older discussion related to rainflow counting algorithm and found some but unfortunately they lead me to new problem. I used some program created by Ian Ward and was able to create workbook for my needs. But for some reason it doesn't always work like it should. Problems occur with some initial data and are related to the array index, I believe. Please find two identical calculation sheets attached with different initial data in embedded excel file. The file "Rainflow Cycle Counting A" works fine but the "Rainflow Cycle Counting B" does not. Can someone advice what is the problem, please? And another question, at the end of the calculations I have another embedded excel file to combine the rows in matrix that has identical values in the first column. For example, if I have values 3, 3, 3 in the first column and corresponding values of 2, 4, 6 in the second column, I would like to have them added so that I have row: [3, 12]. And this should be don

No files to download when in the software download/installation section

when selecting the correct mathcad download i log in enter my details and product code, this then brings me to a page saying that there are no products entiltled to updates, this screen does not follow the step by step guide i was sent and i cannot download the software, i tried scheduling a meeting at 8am this moring and the person never turned up for the meeting. I am hoping this can be resolved quickly as i need this application for college. Many thanks

Hi there What is the difference between ( match) and ( lookup ) function in mathcad prime 11thanks Yusra 

Hello, I am trying to use an IF Statement to check one vector against another.  I would like to return the same value into a vector or an altered value depending on if the one vector's value at a row is above 0 degrees.  I have tried replacing Theta_0 with the value of 0 deg.  Either way I am getting an error that says the value must be a scalar.  Could someone help me figure out how to make this IF Statement function properly?   V/r,Devin

My computer factory reset and I have a student license for MATHCAD Prime. How do I re-download MATHCAD? When I go to the Mathcad quick installation guide and I go here: https://support.ptc.com/appserver/lm/mathcad/download/index.jsp and I enter my product key nothing pops up for me to download. Thank you for your help!

Thanks in advance for any input.  I am somewhat new to Mathcad Prime.  I have generated a range variable sigma_t. when i use this in an equation H(sigma_t):= it does not compute and gives the "this variable is undefined" error.  I cannot for the life of me figure out what the issue is and what i can do to fix this.  assistance would be greatly appreciated!

I want to try matchad for the first time on this email accont and it says that i have reached the maximum number of licese request

Hi, Then I overwritten values for t1 and t2 and test variable result was updated with the new values of t1 and t2: Then I disabled t1 and t2, but the test variable remained unchanged. Why t1 and t2 did not took value 2 and update the test variable result with 4?  

PTC software download does not have a download button for me. I have purchased Mathcad Prime Student Edition 11, but I cannot download it.

Hello All:  I have encountered some strange behavior with the new "vec()" function in Mathcad Prime 11.  An example of this is shown in the screen capture below.   In trying to plot a complex function (the volume of a sideways cylindrical tank), the old way with a "range" for the h in this example gives the correct results (determined independently of Mathcad). However, the h created by the vec() function yields very different results in this instance.  I tried other simpler formulas [e.g, sqrt(2*R*h-h2)] and the results were satisfactory and both results matched.  But as I started fleshing out the equation with more terms, the behavior diverged as per the example below.   The other terms, when isolated, produce satisfactory results.  Only the term shown below in V2(h) presents strange behavior.  More still, expressing V2(h) differently (e.g., algebraically rewriting the expression will create still different but, likewise, still w

Hi   reference topic: Solved: reloading Mathcad in new windows 11 computer - PTC Community I'm upgrading machines to win 11 and trying to re-install prime 3.0 on those machines with a new correct licence file. Installs but cant apply licence.   Machines with Mathcad already on when upgraded to 11 work fine.   Any feedback welcome.  We have perpetual licence.

Hello All, Has the Math software Wolfram become a competitor to Prime in terms of Engineering value? In Prime going back 10 years or so, I used simple loops to get my calculations done.Which these loops are basic to Mathcad and Prime.I have not known Prime for a programming language rater symbolic programming for loops etc.I have come across Wolfram very often when I need something to calculate on the spot using the internet. Thru that I have recently learnt that it is quite impressive.You can set a grid worksheet and have its color light green too like Prime/Mathcad sheets.So, for me that is some cause of an attraction or pull to Wolfram.Especially considering the price.And it is loaded with a full programming language. Tell me am I missing the serious engineer deep thoughts on this?Your comments are appreciated.  Kind Regards,Karl Bogha.

I have tried several times to have the link emailed to me to download the free version of Mathcad but I am not receiving the email. I have checked the spam folders and there is no email.

Good AfternoonI installed version 11 as a trial version but unfortunately the files I'm trying to open are an old version 14 Could you send me a link to a later version that would open these? I had trouble getting the link for version 11 in the email address.Much appreciated ThanksRick
