When trying to create some test matrices in Mathcad 15 for the functions in the attached worksheet, I found that I couldn't create a nested array at worksheet level by setting one element of a matrix to be a matrix.  It's fine if I do it inside a program or if I manually create such an array.Is this a known issue?  Does it still exist in the latest version of Mathcad 15?Thanks,Stuart

Why I'm getting different results for the sum in the attached worksheet with the symbolic and numeric evaluations ?I think I've made somewhere a mistake..., but I cannot find where.Probably I am so far not able to see the forest behind the tree...Many thanks for help, Liv. The worksheet was saved in Mcd11, but same results in Mcd15.

This data reconciliation analysis using Mathcad15-M10, shows an example of flow measurements with optimization of matrices.

Is there a version of Imagination Engineer LE that works with Mathcad version 14

Hello to all,I have to calculate equations for different locations, where the equations are the same but the variable entry data will change per locations.I would like to export the data per each calculation file to a master file where I can put them together in just one graph.Is there any way to do this?thank you in advance,Rogelio

Im new to mathcad and am embarrassed I can't figure this out on my own.  I have a function, f(x)=A*sin(theta) that gives me an answer, however I need to set the function equal to zero after 130degrees. On paper it looks like:f(x)=A*sin(theta) if theta <= 130 degrees       0 if theta > 130 degreesAny help or even a link to a another post (I have looked and can't find one though) would be appreciated.  Thanks in advance.

I am facing unit conversion problem while calculating erosion velocity in mathcad. Any guidance.

Hello allI am sorry to say that this problem is not about a exciting, complex and never seen before math problem. It is more of a simple interface problem. I have included a document that describes the issue, but the essence of it is that i want to be able to define a variable as an equation. More specifics in the document.Many thanks /Mürer

I am trieing to solve one minimize problem.Numerical is OK - see please the picture and the Mathcad 15 sheet in attach.But numerical - problems - see please two sheets (15 and Prime 3.1) in attach.Any help please.The problem of the race (from point 1 to point 4) on the lawn, plowing and asphaltorA a ray of light in a three-layer plate

I have a specified function. However, I want to be able to find both values at an specific intersection. Is there a prime command to do this? are markers able to give you values in both axes or only 1 axis at a time? example provided below.

Hi,The following matrix calculations were completed in Mathcad:My feeling is that the vector solutions for the last two matrix x vector calculations should be equal.  I would appreciate help understanding where I have made an error,Thank You!Rick

Please let me know the steps (baby steps please) involved in making the last simplification in the attached Mathcad file. (I've spent a couple of hours on the web trying to find the answer but the simplification engines on the web, that give the steps, stop at equation 1.)ThanksPeter

I'm thinking I need for loops to insert vectors P, M and V into Q as follows:P0 into Q0P1 into Q3P2 into Q6P3 into Q9M0 into Q1M1 into Q4M2 into Q7M3 into Q10V0 into Q2V1 into Q5V2 into Q8V3 into Q11I need help with the programming and sequencing.

Hello,Please see screenshot below and help me get the items in the Component Wizard to show up again.ThanksJoe

Hi PTC Community,This is a long example problem from a textbook. It goes thru the preliminary steps of the design of a hydro electric power station.You may find it interesting enough to pick up the book yourself. If you need the Prime file please request.

This package, written for Mathcad 15, is a comprehensive solver for a wide range of Data Envelopment Models (DEA). I've used it on quite large models and also for calculating improvement stragegies for sectors of New Zealand's Tourism Industry using inputs derived from Statistics NZ. It covers the usual Constant and Variable returns to Scale problems, accepts either input or output orientation and has the added feature of also calculating Capacity Utilisation - essentially a DEA model, but some of the inputs are fixed whilst others are variable (e.g. Capital Stock might be regarded as a fixed input). There are three solver systems: 1) the solution of either Input or Output DEA models, 2) the Calculation of Exemplars for non-exemplary DMUs and the calculation of slacks - and finally 3)  the Capacity Utilisation solutions for a mix of variable and fixed inputs.The use of the Solver Block is a bit novel as it is completely parameterised and works like a dream!Models can be copied in

Hi,i have got to solve an equation that depends upon itself. I have attached the mathcad file.When i try to evaluat the solution at a certain value of t, i get the message that the evaluation leads to an infinite recursion.Im thankful for every support.Kind regards,Markus

Hi Electrical Engineering Students,If you are interested in power systems protection, here is a paper by an expert presented through his employer a respected relay (protective device) manufacturer in USA.The course I took at graduate level certificate (5 courses with 1 prerequisite) was on this area. This paper is involved, and I remember reading through part III.If its an area that may interest you, the course work is provided at the University of Idaho. There are a few other institutions teaching it in USA.Some protection manufactures do provide courses but they have the theory and problem solving but as a manufacturer they are not like a university more focused to the operation of their equipment and the purpose it serves. Such complex papers do not serve their needs, they want to get the scope of work for a protection engineer covered with respect to their equipment/device. You will not find the depth at the level a professor in the subject will expose to you.Thought it may interes

Hi Electrical Engineering and Electrical Technology Students and Professionals,Substation outdoor overhead bus bar sizing. Some examples may be applicable for switchboards.Large industrial facilities will have a substation at the facility or one constructed near by for it.For your use and or your associates.

I have seen one problem in Internet (www.anekdot.ru) and have solved it in MathcadPlease comments!

Hi Electrical Engineering and Electrical Technology Students and Professionals,Substation grounding/earthing example - simple short and principled!This example demonstrates the design steps in the earthing mat/grid in the substation.You may use it for studying earthing. Large industrial facilities too require proper earthing for safety and proper operation of protection devices.For your use and or your associates.
