Hi....I am trying to compute the standard errors for specified return interval years using bootstrap methods..I have computed  the bootstrap values at  the indicated return intervals but am not able to compute the standard errors of these return intervals  and could  use some help.ThanksDick....

Hello Expert,I have some trouble with Jacob built in function. when I calculate the partial derivative with respect to L1,L2,...L6, the answer should be 2L1,2L2....2L6. but the feedback from Mathcad shows all zeros matrix. as long as I know the answer should be diagonal matrix with 2L1,2L2,...2L6.I am really appreciate if someone can give the advice. Thanks in advance.P.S, enclose file, you can see the last equation, called Eqn(X,Y,Z,r.1,r.2....L.1,L.2...L.6)=~~

How can I change floating point in MathCad Prime 3.1? I am tring to short this 41.666666666666666667 (^ x 3)) (* 1058.3333333333333333 (^ x 2))) (* 8956.25 x)) 25251.75)  but I can't!!!and how can I change the equations shape from fractions shape to linear shape like this for example {(10*x-81)*(5*x-43)*(10*x-87)}/12 ??Message was edited by: ggg hhh

I have a large worksheet that was converted from 15.Today I made a number of corrections to some of the assumptions that new data has clarified.When I try to save the file, I'm getting this error:similar to the error I receive when I'm trying to open a Prime 3 file...the information in the log file is uninspiring.here's an extract:Exception data:File being saved: ..\Desktop\48V ph1 dcdc Full bridge 2tx 25 1 2016 with litz - Copy - Copy.mcdxSystem.NullReferenceException: Object reference not set to an instance of an object.   at Ptc.Controls.EquationControl.GetDisplayMatrixCell(IMatrixResultNode matrix, MatrixFormat matrixFormat, Int32 r, Int32 c, Boolean useEagerMatrixForSmallMatrix)   at Ptc.Controls.EquationControl.ConvertToEagerMatrix(IMatrixResultNode originalMatrix, MatrixFormat matrixFormat, Boolean useEagerMatrixForSmallMatrix)   at Ptc.Controls.EquationControl.ConvertToDisplayMatrix(IMatrixResultNode originalMatrix, MatrixFormat matrixFormat, Boole

Dear All,I am new to the mathcad. I tried to solve the variable d, which is diameter of the pipe.Where I am wrong? I could not solve for variable d.

Hello,I am new to Mathcad. I am having hard time to solve a simple matric equation like this mx is a 2 by 1 matric and  '2' is expected to be added to each row. Can any one please help me.Thanks

Hi Friends.I have a question to day. I am learning Mathcad 3.0, when I look up video PTC Mathcad Prime 3.0 - Features and Functions - YouTube  at 1:40 min.What is video use tool ceating ID same video at 1:40 min. Can you tutorial creating same shap I.thanks.

Hello everyone,I hope everyone is doing great. I have three sets of data like:A= 1,3,5,6,7,8,9B= 2,3,4,5,6,7,8C=13,15,16,19,20These data s are field  raw data and I need to fit it to make a non-linear regression equation. I will be obliged if you can help me out with it

Hey I'm a student and at school we use mathcad 14. I decided to download the free mathcad express prime to try and be able to work on my homework and class problems outside of school. I've tried typing in exactly what we did in class (which worked perfectly) into the free mathcad express and nothing seems to be working and can't figure out how to type some of the functions into the program. Here is the part that was giving me the most trouble. the left is what we did in class (on a word document) and right is my attempt at inputting it into mathcad express.Thanks

See please No one can figure out what's going on in this children's fruit puzzle One solution in Mathcad. Or I do not understand someone?

I am going to serve as teacher assistant in a construcion course at my universty were i will be grading beam design assigment. I have calculated everything in mathcad 15 so far. The students will have to determine the height of the beam by fullfilling a criteria.I would like to put my mathcad file on the internet were the students can select the diffrent parameters each student have. mostly diffrent material propertiesand there they can see if they have choosen a height that fullfilles the specifed criterita. Basiclly I want the student to choose their parameters from a dropdown menu or something and then the calculations will be performed based on that andthis i want them to be able to do on a webpage. is that possible?

Sometimes when trying to select a portion of a big equation using the Shift key, you overshoot your mark and have to cycle through it all over again.How about a SHIFT-SPACE to go backwards??  Can PTC put this in?

Hi! Do anyone know if its possible to hide parts of my calculations? I solved an equation and got some ugly looking, precise answers. I only want to show the approximate decimal answers.  Thanks.

Hello,can anyone help me as with which type of non-linear regression function should I proceed to fit three sets of raw data.Thanks

Hi,I want to solve trwo consecutive differential equations in Mathcad 15, which is like following picture,Actually, I want to get the plot of S(r) with r. In addition, "r" ranges from 0 to 0.001. I don't know how to deal with my error, hope to get your help. Please, kindly find the attachment about this task. Thank you very much.Jason

Is there a Possibility?I need Komma in Excel and need to adjust in MathcadThx 😃

The following is an algorithm for the calculation of the eigenvalues of a square matrix. It is present in almost all the "classic" texts of numerical analysis. It is an indirect method and is an ill-posed problem as opposed to the modern ones (for example, QR). I, however, did not find the theory that allows the calculation of the eigenvectors, at the end of last century, I developed the algorithm, shown below. The accuracy is to be verified.

Hello,usually I define function as function of variables. The latter being scalar.How can I define a function with the variable being a vector?examplefunction(p):=p(1)*x+p(2)with p being a vectorthis gives me errorThank you

I work with WIN7, WIN XP, and WIN 2k. I use MCD-15, -11, -2001.In all cases I find an error when calculating a definite integral. The error looks as follows: the location of a constant "a" inside the integral leads to a different solution compared with the case with the consant "a" outside the integral. This behaviour hurts the basic mathematical relationship in (1):The result of a simple calculation approach can be studied in the following graph (solid = wrong = left side of (1)n; dotted = right = right side of (1):In most cases it won't be possible to move constants outside the integral, hence, there should be a bug correction asap!

Hey,with nice help in the community i finally made the Loop to calculate LOadcases and exporting to excel.Now i would an automatical saving process after every step i.For further documentation purposes i need a mathcad file for every step i.In the saved Mathcad File all values should appear for the actual load case.Example:In the saved Mathcad File i needbut with the inserted i.....Result of Load Case 1 as value (i=1):nexto the Result Vector i need the "OK NOK" condition weather is true or notHopefully there is anybody which can help me.

I'd like to know if installing Mathcad 15 in Windows 10 goes smoothly.  Has anyone had recent experience?Thanks,Jim

Hi, is it possible to call some built-in matlab functions (eg, Laplace and Invese laplace transform functions) to solve various systems of differential equations via Laplace within Mathcad? The equivalent functions in Mathcad are too complicated to solve differential equations. I am working on a long Pharmacokinetics project in Mathcad that requires solving differential equations via Laplace Transforms.Any help is very much appreciated.
