More about free mathematical software from Walking Randomly SMath Studio is an extremely promising project that has already caught the interest of many Mathcad users (it even has basic compatibility with Mathcad’s file format) and is well worth the download. Composition of Logarithms simplification added into Symbolic Library.Native support of functions added: abs(.), trunc(.), mod(.), round(.) in Symbolic Library.Function if(.) can be used in symbolic calculations now.Added support for Infinity into Symbolic Library.Functions for(.) and while(.) condition evaluating improved.New functions implemented: eval(.), polyroots(.), reverse(.), sort(.), rsort(.), csort(.), normi(.), norm1(.), norme(.), linterp(.), cinterp(.) and ainterp(.).Added ability to convert English symbols of the Math and Text Controls to Greek characters with a Ctrl+G keystroke.Multi-threading implemented for the Plot Controls.Every page now has its own thread for evaluation – The user can evaluate pages even if evaluation of one of them in progress.

A small selection of the improvements is shown below but you should head over to the SMath forum to see the full list of changes The latest release, version 0.85, was made available yesterday for all platforms and includes a lot of new functionality combined with a set of bug-fixes. It is nice to meet you.Smath Studio is a freeware alternative to Mathcad developed by Andrey Ivashov for Windows, Linux and Windows Mobile.
On the other hand we are working on the same thing in a sense (this function is the excess flow in a 3 way control valve when you have different circuit pressure ratios and valve authority (alfa and beta) for different opening of the valve x). Probably the question I'm asking for you (and everyone here) is very simple but as I said I'm at the very begining. I'm amazed with your file however I'm a bit newbee and I'm a bit lost in that. Infact I should do it for 16 different functions and that's why I'm trying to avoid it. When operating on vectors, poly and roots are inverse functions, such that poly(roots(p)). The reason I don't want to use your approach is to avoid large equation size When I substitute x with another function lets say substitute every x with exp(2.32*(x^2-1) etc it would be even larger. The poly function converts the roots back to polynomial coefficients. What you wrote in the reply is exactly what I'm looking for but I couldn't manage to get it through would you mind uploading an example file for me? Because this is where I'm puzzled: Can we use a range variable in Maximize function in Mathcad. I'm uploading one of the files that I'm working on, in principle it is the same as a f(x):=a(sub i)x^3+6*x. RE: maximize function over a range of constant simyotic (Mechanical) Note, my worksheet allows me to find the coefficients for any linear third order differential equation. Where C is a constant you will approach but not reach.īetter yet is to convert your f(a,x) to minimize error so you can just use f(a,x) = 0 like I did. In your case you need to replace the IAE(A1,A2) with f(a,x) = C. That is because I am trying to get the error close to 0. I have an equations where IAE(A1,A2) = 0. deltacomp sys.com/pu blic/NG/Ma thcad%20-% 20IAE3.pdf Note, I couldn't simply take the derivative of the resulting equation and find the minimum so one must use an optimizer.įtp://ftp. Here is an example of finding coefficients of a differential equation that minimize the integrate absolute error. Do you have a better example? It would be good to know what you are really trying to do.
In your example 'a' will always be bigger at x=1. I have found minerr works better than minimize. Therefore you must subtract your f(x) from some constant that will not be exceeded. Normally the minerr function is used to minimize error. The reason I mentioned about taking the first derivative and so on was because, it(derivative=0 ->solve block for a range of constants) is another way to find the maximum of the f(x) for a given "a" value.
