I got advice to use "vectorization" But I wonder something.I saw the book and I knew that "vectorization" is just possible to calculate about same raw and column.But I need to know total calcuation values. For example a=0,1,2,3,4,5 b=1,2,3,4,5y=ax*bif I caculate by using "range variable", I get total calcualtion values. in case <a=0,b=1> ,<a=0, b=2>.....<a=0,b=5> <a=1,b=1>, <a=1, b=2>.....<a=1, b=5> . . .<a=5, b=1>, <a=5, b=2>......<a=5, b=5>I want to get values following.I couldn't have used "vector" because I thought that I couldn't get it.

I could success to express theta look like "range variable"But I can't get "alpa"I guess the reason why I can't get values is due to "beta" I got error. error said me that the unit is not compatible.so I don't know which is wrong.

I am doing some strain evaluation for dents in natural gas pipelines. I am looking to interpolate matrix to generate a larger matrix with more points. I am not sure how to go about doing this in mathcad. My Matrix can vary in rows in and columns based on the user input. For this example 18 rows and 85 columns. Essentially I am looking to have more data points in order to evaluate the dent geometry.

Hallo.I have some trouble with this.I have to find the polar notation and rectangular notation.I can find the answers from my normal calculator. But how can I type it in mathcad, and solve it there?The answers are 340∠-10.9 and 334-j64.3

Hey,at the moment i´m calculating the massstreams in a powerplant.For the calculation there is a for-loop necessary because one of the last streams is going back to the beginning of the calculation.My problem is that the for-loop will not be calculated while using Units (like kg/hr or mol/hr).I added a simpel example which should discribe my problems more accurate.The output of for-loop should be a Matrix with different Units like [kg/hr] for the Massstream and [ ] (no Unit) for the iteration number.

Hi,I am trying to install mathcad 15 free 30 day trial, but I get an error when trying to obtain a trial license.Invalid host id errorAny help appreciated

Hello, I having a problem with Minimization with 6 paramaters. I have attached the worksheet. i am not able to find the problem. Its calculating, but it doesnot bring the answer. Pls kndly check my worksheet. Thank you

Hello,I a'm a student and i need help witch taskGiven a triangle defined by 3 points with coordinates(x1, y1) (x2, y2) (x3, y3)Determine the center and radius of the circle of the triangle. Draw a triangle on a graph and a designatedcircle.i don't understand this sorry for bad english

Hello,I have an equation with one uknown on both sides and would like to iterate to get the value of variable, however the find function brings error, I think I am following others recommendations (several youtube presentations) but still no result. I have more equation like this to solve and would really do with advice what I am doing wrong.I am new to Mathad.

Hi,I am attempting to solve a linear system with mixed units, but I am having great difficulties. I have read that 0's within the matrix must have assigned units. However I still get errors.Worksheet attached - linear system on page 2.Working in Mathcad 15Any ideas? Thanks

Hello,I am having trouble using the solve block, specifically the find function. I am completely new to this, and have tried researching on and double checking variables, but I cannot seem to find the problem. I have attached the file.Thanks for any ideasEDIT: I am running Mathcad 15 trial on W8.1

Hello everyone,I am trying to create a plot to find the critical phase angle affecting a pipe.When I created the calculation in Mathcad15 everything works fine. See the file attached.When I reproduced the calculation in MathcadPrime3.0, I am getting errors such as "the variable is undefined", "plotting failed", etc. See the file attachedCan someone please let me know how to fix the MathcadPrime3.0 calculation?I am having trouble calculating the lift of drag force for several values and then using these to create a plot. If input F(4) or F(6) everything is fine. But if I say F(x), and x is a matrix with several values, then the equation crashes.I would really appreciate your help.Thanks!-Ritchie

Hi guys,Can you please help me with the following problem. I am not an expert in mathcad.i want to draw "t" vs final "finalCoOEPcon" in the attached mathcad sheet and Mathcad keeps giving the error that the "value must be real" which i believe is real.so i have two questions:1- is the way that i wrote the "equation A" is right in mathcad for solving for "t"? 2-can you help me with some hint that how i can make this curve please?thank you very much

Hello,I'm wondering if it is possible for MathCad to do an optimizing routine using max or min but with a given set of parameters. An example is one of the attached in where I use u(x) and g(x,r), where I want to allow for the input of r during the optimization. Additionally, would it be possible to graph the optimized set as a function as well in terms of a variable x & r. (for any given r, the maximum x is a set value as the rest of parameters are just scalar values, thus I would like to get the optimized value of x as a function of r) I'm assuming the opt x for a given r can be done via a vector output from a solve block routine as a function?

I don't know well wht I got error cotinually. I am shy to post often.

For example, is it possible to track red line on green line?I searched some site to know it.But I don't know well, is it possible?

I posted a few days ago about same question.But I can't understand well and I think it is not accurate about "polyfitc" when I used it.For example,RNodes(2.8667)>>>Aero Twst(13.308), RNodes(2.8667)>>>chord(3.532)I want to express such as upper.it means that they are related mutually.when I posted such as similiar question before, I got reommendation to use "polyfit" But it was not accurate compared to original values when I graphed.And I got another answer, but I coudln't understand well.so Could you help me again ?< I need to use original values without change a little>

Hello, i have problem with Mathcad 15 how to calculate 4(x-5)(x-6). I want receive polynomian 4 x^2 + 44x + 120.I also have a second problem, when i calculate matrix i receive simple table like in Excel program, how to change view this matrix to ordinar view.

I developed this analysis for a court case I was working on.  I operated on about 100 years of precipitation data. The mean and median of the data set are quite close together.   I developed probability plots as well as histograms of the data.  I then did an autocorrelation analysis.  Turns out the annual precipitation data appears to follow a normal distribution and the data is not autocorrelated.  It therefore appears that statistical tests for the normal distribution can be used to make predictions about future precipitation amounts. 

hello everyonei have this problem guys. ive been trying to solve an equation system for a thermodynamic problem using the given/find commands and when i try FIND i received this error " this variable is undifined". i really dotn know whats wrong with my equation system. if anayone could help me out and explain whats the problem in my MCsheet. i would apreciate it.the file is attached.

Hello! How can I find symbolically the ex,ey and Phi variables? I have tried with solve block, but the solution was the guess value.See the 3 equations in the attachmentThanks in advance!

The question of how to save the state of controls in a Mathcad worksheet comes up so often I decided to post the answer somewhere I can easily find it and post a link to it!There are two approaches:1)  Save the state of the control in the worksheet custom metadata. This  method will work in versions 13, 14 and 15, but not in versions 11 or  earlier (I"m not sure about version 12).2) Save the state of the control in a textbox. This will work in all versions 11 and later, and maybe some earlier versions too.There are some things to be aware of when using them.Firstly,  in version 11 if the result of calling a function is not displayed, and  it's also not assigned to any variable, Mathcad does not calculate it.  That means that if you use method 2 and put the SaveData function in a  collapsed area it will not work. In version 12 and later they removed  this optimization, and therefore it will work.For  the second method, if the Listbox is off s

When I close the worksheet I can not save a listbox selection that is dependent on a previous listbox selection. The first listbox I was able to save the selection using the Metadata , but I could not figure out how to get it to work with the second list box.
