Good day,

So I was shifting from Mathcad to SMath and I can't seem to do this properly. How do I get around graphing this response spectra.I'm quite new to SMath so please be understanding if I don't know of some functions within the program.

This is hot it works finely in Mathcad, what would be your suggestions?



Thank you for any help,

Here you have your file fixed.

The issues:

The function was made using "while", that is a loop iterator. You have to use if(), or cases() if you prefer (the latter is part of a 3rd party plugin).


The evaluation for multiple values has to be done using vectorize() or alternatively by a loop


The built-in plot variable is always x for static plots, t to add animations.

An alternative way to write boolean of your function is using ltle() function.
It is one of functions of Custom Functions Plugin.
