I'm trying to use the "match" function and having a very ridiculous problem. If there is no match, the function returns error. Works fine if there is a match. This makes it useless. As best I can tell from the documentation the return should be "-1" if there is no match. What obvious thing am I missing? 

Hi,Problem:     The plot result should be like below:  

Hi,What is the reason that with N = 4000 I can see the points more pregnant, but with N = 5000 points are visible poor:      

Hi,     It should look something similar with:    

Can anyone tell me the correct syntax for using trigonometric functions?  When I try it, I get an error result that says "missing term or expression".  All help appreciated

Dear Colleagues,Some time ago, I downloaded a worksheet from the following location: https://community.ptc.com/t5/Mathcad/Study-1-Properties-of-working-fluids-coolants-and-structural/td-p/266560. I would like to create a 3D plot illustrating the data distribution from the generated table (function). Unfortunately, I have tried various methods but haven’t been able to figure it out. I mean somethin like below:I'm using Matchcad Prime 10.

It shows an error although it is a vector . WHY? 

How can I find the longest vector. I have q which has 27 vectors and I want to find the longest vector which has the most values . maximum function works only for scaler not vectors . this is on the  2nd page of my sheet 

I need to draw this plot for the effective stress. However, this error occur ..How can I fix it? 

Hello,I have separated a small for-loop from my calculation. This also works correctly.Now I would like to save ai for each i or rather access individual values. Furthermore, I would like to draw a graph. y-->ai and x-->iI would be grateful for any help 🙂Kind regardsMax

Hi,How to find all roots of this equation:

Hi,I saw somewhere in wolfram mathematica that it is possible to obtained relatively "easily" the solution of this partial differential equation. Is it possible to obtain somehow the solution also in Mathcad Prime 10?    

Hi,

Hi,Calculate the total interest paid:  

Hi,  The problem I'm currently working on primarily uses 2 decimal places. However, at some point in the sheet the decimal places change to 15 places unexpectedly. For the regions where this problem occurs, the math formatting menu is completely greyed out, although text formatting is still functional.  Any help with this? Thanks   

1 ) Apparently, there is no substitute for copying and pasting a block of Excel cells in Prime as we could do in MathCAD 15.2 ) This has forced me to use READEXCEL but unless I shorten all of the file names and work sheet names (in the READEXCEL function), the line runs off the right side of the printable area. I tried inserting a line break (Ctrl+Shift) but that didn't do anything inside the READEXCEL function. Is there a way to break up the READEXCEL function at the comma? I don't want to rename files as that will make documentation less meaningful. I shortened the path to ".\" but the line is still too long.

Hi,      

Hi all,  As shown in the attached image,when tf=0.055 is equal to tf.min=0.055, the results should be "OK" since tf must be bigger or equal to tf.min as stated in the if statement  does anyone know why the calculation does not capture the equal sign and produce an "OK" output when the value of tf and tf.min are equal??Thank you in advance.

Hi,How to do this kind of sum?

Hi,How to calculate this sums:  

Hi,Why without adding that else NaN at the final the plot is showing the waveform, but after that else NaN was added at the final of the function then the plot failed?    

Hi,I do not understand this error in which root function found a number greater than 10^307, as we can see from the plot that on the interval [0.1,10] the magnitude did not go above -1, nor above 1...   On the other hand if we specify also the interval [0.1, 10] inside the root function then the root gives no more this error, and can calculate.   I do not understand why in the first way root function give that error, as I expected root function to be evaluated between [0.1, 10] interval also in the first way, given only the guess values inside the root function, and not specify explicitly the interval.  

Hello dear community, I have a problem determining the roots of my function. What I want to know is the values ​​of the Y points (black color) for each graph. Please if someone can help me with this problem. My version of Mathcad Prime V.8.0Thank you for your attention.. Translated by the moderation using Google Translate-----------------------------------------------------------------------------------------------RaicesMuy buenas querida comunidad, tengo un inconveniente en determinar las raíces de mi función. Lo que quiero saber es los valores de los puntos de Y (color negro) para cada grafico. Por favor si alguien me pueda ayudar con este problema. Mi versión de Mathcad Prime V.8.0Gracias por la atención prestada.. 

Hi all, can anyone teach me how to produce the results based on the if statement as shown in the attached picture? Thank you for your kind help:')  

When I add units it shows this error . How to fix it and why it happens?I attached the files usedit works with the first column but not with the second and third:   Thanks in advance
