  can somebody tell me why this is saying units are not compatible, it works when I take it out and do it by itself??Thank you

Good morning everyone!How do you explain the out-of-memory status in this case (see photo) when Task Manager shows that only about 9 GB of 32 GB are used? Thank you to everyone who can answer this.  

Hello, After subtracting two vectors, how do i set the element value to zero if it is negative? P9 sheet is attached.  Thanks,Sam

I create parametric bitmaps that depend on the values of the calculated variables using the READ_BLUE function.How to insert a numeric value into such a picture as a bitmap that changes depending on the calculated variables?

I can only find one question posed on this and the meaning of the green question mark wasn't provided. Nothing in the online help either. Mathcad also indicates that there are errors in the included document, but there aren't. Wasn't sure if the green ! was related to that. The included/reference document expects to see some values defined before it because the included document does calculations based on the pre-defined values. So in actual use with required variable definitions provided prior to insertion of reference doc, everything should be fine. When you drill down into the reference document, Mathcad acts like it knows nothing about the previously defined variable (which sort of makes sense) and gives me errors (red boxes) on some of the calculations I can't remember, but I thought Mathcad v15 had an "if defined..." function so you could make local definitions if something wasn't already defined. Am I remembering correctly? I haven't seen such a function in Prime (v11)

Hi, How can Mathcad 15 skip steps in a loop with skip stepping dictated within the loop? Here increasing i by two inside the loop only affects the one step not the counter i which jumps back to 7? Any ideas as want to skip one or two loop steps within loop dictated by calculations within the loop.   Cheers Terry

I created a worksheet in Mathcad PRIME version 10 that reads data from a text file and creates several graphs.  I have 100 text files to read and they are all numbered sequentially (e.g., "file#.txt").  The file that is read is controlled by a variable in my Mathcad worksheet (in conjunction with concat() and num2str() functions).  Currently I am manually changing the variable in the worksheet that controls the file that is read in, refreshing the worksheet, and then saving the file as a PDF (and manually typing in the desired name of the PDF file).  Is there a way to automate this so I don't have to manually change the variable 100 times and manually type the desired name for the PDF file?

Hello, I am trying to build a Mathcad sheet to find pile capacity. The maximum number of soil layers available is nine (9). The user can choose to use all or, some of the layers within this 9. I am trying to build a logic to assign unit weight based on the layers I have subdivided to. The issue is if all layers are not being inputted, then the logic for unit weight says "Array Index invalid". Please help on this issue, my version is Prime 10. Thanks

Hello All Depending on the magnitudes of the intersection drifts, Drift1 and 2, the supporting member ( support 0,1,2,..) might have a uniform snow load from drift#1 and an additional triangular drift from drift#2.  I still have few "minor" issues.  I have some questions inside the sheet-Prime 9 in red text.  Thanks,Sam

Hello All, I have attached a Prime 9 sheet. I am trying to calculate  the uniform load on several members resulting from triangular snow load. i have included my instructions as to what needs to be accomplished.  Thank you for your assistance!Sam

This is really 2 questions, both relating to text blocks in Mathcad 10:1) Is there a way to make it so hitting Space or Tab after a math segment in a block of text doesn't move the whole line over?  In any other program, Tab or Space after text just moves the cursor over, not the entire line.  I haven't figured out how to get it let me move the cursor over in a text block without it first trying to move the entire line and me having to go and backspace after I'm all done with the line (hitting Tab again will move it over even further).  How do I get it to stop moving text/math that's left of the cursor when I hit Space or Tab on a line with text/math already on it? Example:This is how I want m = ¾a + b³ <Tab>                          to look                  This is what happens if I hit Tab after m = ¾a + b³ <Tab> and text continues here wi

New Mathcad 10 user trying to get familiar with the program before I need to use it for a new job, and I am getting frustrated with how difficult this program is to work with. Supposedly Mathcad is designed to be able to do a mix of text and math, but I am finding that writing text is agonizingly difficult and buggy. In text blocks, it's manageable, but tabs don't line up, it's difficult to stop underlines and bold (4/5 times can't just ctrl+u to stop underlining, have to keep typing then go back and highlight the text and ctrl+u to remove the underline. Same with bold), and it likes to add and remove new lines seemingly at random. In text boxes, it's almost impossible.- I typed an X and it jumped down to the next line all on its own- It did this again when I did a special character like Φ or µ- I typed something on one line in plain text, I hit enter and start typing on the next line and its suddenly now underlining as I type, though none of the other text in the box is

Hi, i have used too many hours trying to get the plot work but without success. Plot worked in mathcad 15 with normal plotting tool but need to convert calculation to prime 11.thx

I have recently updated my computer to a 64 bit Windows 7 platform. I am now getting an error while using MathCad 14.0 M020 on spread sheets that have worked previously using combo boxes. The error is "Microsoft VBScript runtime error Line16 Error0 Object required: 'ComboBox'". And when I try to insert a Component-Scriptable Object, the Microsoft Forms* selections are not even available as on option. During the initial install of MathCad 14 the .NET Framework prerequisites were not installed from the CD. I have manually installed the .NET Framework 3.5 and the Microsoft Report Viewer which includes the Microsoft Forms. I also upgraded my MSXML 4.0 SP2 to MSXML SP3. I then uninstalled and reinstalled MathCad 14 and am still getting the same error. Has anyone came across this before?

Is there a way to incorporate the arrays MEOP, Proof, and Burst directly into Table 1 rather than do the Math outside the Table? See attached Mathcad sheet. I use Mathcad Prime 10.0.1.0. I appreciate your feedback.

I have been working on a task in which we are to obtain the maximum response of an elasto-perfectly plastic SDOF.  The main reference is: Introduction to Structural Dynamics, by John M. Biggs, 1964. In the second chapter, they provide these tables with the maximum response of a SDOF to different types of load pulses (rectangular, triangular, etc Figs 2.23 to 2.26). See the figure for a rectangular load pulse:as you can see from the graph, the maximum response is represented by the ductility factor Mu, ratio of the maximum displacement to the elastic displacement of the system. Mu depends only on the ratio between the duration of the pulse (td) and the natural period (T) as well as the maximum spring force (Rm) and the maximum load (F1).In my case, since we are conducting a sensitivity analysis, it is not very practical for us to be retrieving the results from these graphs for every analysis we do.Therefore, I proceeded with writing my mathcad file that obtain the complete response

Hello,I'd like to perform a multiplication procedure between two vectors. I am getting an error. Prime 9 sheet is attached. Regards,Sam  

Hi,[using MP 11].I'd like to build up a matrix (n x n, square and symmetric), with the help of a loop.The problem is that each of the terms in this matrix is the second partial derivate of a function of n variables . I couldn't find a way to include this in a program (Match of the variable and the loop counter)My goal is to program in a way that I don't get any "red square" or "this variable is undefined" in the layout. In the enclosed sheet, the terms of the matrix are colour-highlighted. (The context is civil engineering, and the determination of the buckling factor of a column, here with a varying cross-section and varying compressive force). Eager to see any insightful idea! Thanks.

Hello, I have two arrays H and H_end.Pile_vec.total. I am trying to match the numbers between these two arrays and get the corresponding index number from H_end.Pile_vec.total. I have used the match function whic works for the first one only and not for the rest. Please help. My version is Prime 10.
