Mathcad

By Faouizi Amar Displays curve-fitting non-linear models using the Gauss-Newton regression method  Important for many industries  Shows how a FOR loop iterates through the algorithm until convergence of the model parameters is reached using Mathcad's in-line programming capabilities      Curve fitting is often used to analyze and interpret experimental data, which is usually a large collection of points. The goal is to find a model function that fits the trend and level of the data. PTC Mathcad helps you to do this.       When fitting data to a particular model, it is common to transform the model to a linear one and then use some type of least squares regression. In many cases, it is not possible to transform the non-linear model into a linear one. Sometimes the transformation is possible but results in loss of sensitivity. Under such circumstances, direct non-linear regression should be used. There are many algorithms that have b

Can anyone help me solve this equation? I tried everything but couldn't manage it.   

  Building a new Dell 7720 laptop to run everything from modeling, Mold Analysis, MathCAD, Bunkspeed, Keyshot etc. Already getting the NVidia M5000M GPU.   1. With Creo 4 starting to support multithreading is it now finally faster to go with Xeon? 2. Since I'll be turning off the onboard GPU that isn't a deciding factor for a CPU 3. Which do you guys recommend?? Leaning toward the E3-1535M V6 for the fastest clock.   Thanks!!!

Hello all, I have two simple functions similar to each other. One of them shows different values correspond to different values of x, but the other one only shows a unique value. I wonder if it is a Mathcad bug. How can I have both functions give me values correspond to those of x?

Hi I am doing optimizing, and need to minimize the  error below . (by using Minerr in mathcad)But before that,  problem is this error.

Hi everyone, I would appreciate if someone would like to share his/her experiences concerning the numerical integration function. I am aware of what the help says, namely that "Sharply peaked integrands, or functions whose shape is not readily characterized by a single length scale, do not evaluate accurately. This is the nature of numerical integration. Accurate results may be obtained by breaking an integral into pieces and separately integrating around the peak and away from the peak.".  I am experiencieng some difficulties integrating artificially generated earthquake acceleration time histories (discretized, of course, for example with a sampling rate of 100  or 200 Hz) to velocities and then to displacements. Admittedly they are peaked (see attached example), but I am surprised how often the standard integral function of MathCAD 15 fails to converge (with autoselect, or with Romberg or Adaptive).  The convergence problems happen if I use linterp

Hi all, I have a function with 6 loops (0 to 5), but when I try to keep track of changes of two parameters (alpha and betta), they are returned as the last members of two 1by12 vectors. The numbers of my data sets (x and y) are exactly 12, but I dont know what is the relationship between the these two. I wonder if somebody could take a look at it?Best,   Physical Mathematics

I am using Mathcad Prime SDK 3.1 for Mathcad Prime 4 to automate some time consuming calculations and worksheet management. As described in SDK, the communication is done over an ApplicationCreatorClass() call. This works more ore less fine but I cannot control to which running Mathcad instance the link will be performed. My question is: Is there any way to establish connections to different  Mathcad instances running on the same computer?

Hi   Need some help to create an equation for the 6 cases of  linear graph I attached the mathcad prime for your reference.  I cannot make the graph straight using  this formula ( y= mx+b)  because x  should be   in  logarithmic  distance       Physical Mathematics

Is there a built in function in MathCAD prime that can create pair combinations of integers from two dissimilar length vectors filled with integers? 

Hi,   Earlier i am able to protect / Lock the area with password in Mathcad 15. But i am not able to get the option in Mathcad Prime 3.1. So please can some one explain the process. Addition of snaps are appreciated.   Thanks, Prashant Pandarkar

Recently our company installed SolidWorks PDM Pro for document control.  PDM Pro is similar to PTC Windchill.  More of our office documents are getting saved and controlled using PDM Pro.  Does any one have experience with Mathcad 15 and PDM Pro?   Cheers,

There is no Polls now in this community, but I ask you what we must do now 1. Change formulas in references books 2. Change tools in Mathcad, Maple etc 3. Nothimg 4. Others See the picture please

The Mathcad 15 M050 release that supports Windows 10 was supposed to be 2nd quarter of 2017 according to the Roadmap.  Has anyone heard anything at the PTC events on when this is actually supposed to hit the street?Thanks,Jeff

I heard that Mathcad 15 M050 will be updated with newest C++ and .NET. Is it true?  

I want to put out a total of excel's table by Mathcad. I could inport excel's table. I can't calculate. Is there any way to calculate something easily?

Please looking at the function in adamsBDF, why is it red?   Thanks      

Hiı need to take some plot and ı start to define eqn, first eqn dependent one variable second eqn dependent 2 variable third eqn dependent 3 variable  and it is going increase thus the equation will be very long is there any thing to shortly define this kind of eqn?   thank you 

I have been using MC14 for a while without any problems. But recently when I try to start it (it seems when I have not used it for a while), I get the message that no license file exists. Then I can go through the process of retrieving one over the net by entering my product code and using my PTC account username and pw (same as for the forum). Does anyone have suggestions for avoiding this in the future? (I have been unable to find where MC actually puts the license file on my computer).

Hi,   We have created one CAD model in Creo parametric 3.0 and embedded one mathcad worksheet (mathcad prime 3.1). in this we have some inputs from creo to mathcad and some outputs from mathcad to creo.   So once we update input in creo parametric 3.0 we need to open mathcad file and click on Update input and then click on save and push. We want this process should be done automatically after regeneration of model.   So please can i let know, how we can update input parameter to mathcad and output from mathcad to creo automatically. (No need to open embedded worksheet, click on update input, click on save and push, close worksheet).   - Prashant Pandarkar

I have a problem with a solve block constructed in MC15. As long as I use a single input variable A the sheet works fine. However if I want to calculate the values for a changing chamber length it does not work. I assume it is something simple but I do not "see" it at this moment. Any help would be appreciated.

Hi Folks,   This is just a follow up on an earlier question about downloading V15.  After a couple days of frustration, the problem in moving a license to a new computer, a PTC installation engineer got it installed.   The root cause seems to be that the Product Code I saw when I clicked 'About Mathcad' was not the one they needed.  Apparently, I was expected to know this and to go looking for a different one on an old email from PTC.   The installation engineer, who was very helpful, said the best way for me to get this information to PTC was through the Community.  Not sure why PTC is trying to make that my job, but I promised that I would make the post, so here it is.
