Sorry to be so slow on Smath. Some thing work like Mathcad and some don't. I need help with the correct syntax for the interpolation function linterp. I have tired all combinations of syntax that I can think of and none work in the attached Smath file. Help would be appreciated. RMD CALCULATION.sm (16kb) downloaded 24 time(s).

I don't think vectorize works with this function. It is expecting a single value in argument 3. Checkout my linterp2 function in the attached. I think it does what you want. RMD CALCULATION.sm (19kb) downloaded 28 time(s).Note: In my program, it is not necessary to initialize the result. However, I have found that in cases of large vectors, it speeds up processing time to initialize a vector to the expected size and then fill in values. I generally just do this as standard practice now even if it's not necessary. Edited by user 15 February 2019 02:37:28(UTC)

Thanks much. You are a real help. I did not realize that the interpolation functions required additional programming. I incorrectly assumed it was like Mathcad. Many things are like Mathcad, but clearly not all. Thanks again. Reg

No problem!. Welcome to the forum. There are a lot of people here who are regular contributors and will help you with questions you have. For me, it's why I primarily use SMath for my calculations.
Regarding similarity/dissimilarity to MathCAD... once you start using SMath more you'll stop thinking in "MathCAD" and be able to think in "SMath". As a former MathCAD convert myself, I really started to come into my own when I stopped thinking of how I would do things in MathCAD and started figuring out how best to use SMath. |

Read carefully: linterp, cinterp are 1/1 Mathcad Smath ainterp has special virtues not found in Mathcad. Smath linterp, cinterp, ainterp are 1/1 Mathcad as interpolation. but are 0/1 as scalar functions. In many instances, it is possible to recast the problem in the form of infinitesimal analysis. I found no way to render a_c_l interp scalar Mathcad style. Though, I have the Mathcad code. Don't confuse yourself, a_c_l_interp they plot on the canvas, i.e: they plot scalar. scalar is a kernel internal vanishing iteratorNext question: please attach the Smath document. Jean

Jean, I appreciate your attempt at helping me. Unfortunately, I am new to Smath and don't really understand your syntax in your attached sm file. See my comments in the attached file.

Just a note. Pay attention to the plot by Alvaro. He uses often neded lele() function (Custom functions plugin) for checking if the value is in a range: Xmin<=x<=Xmax Regards, Radovan |
