Hello,

I am getting this error when trying to plot piecewise funtions. I've search trhough the coummity for may solutions but I can't solve my problem at all. Could you please help me?

I attatch the mdcx and a pdf of the function.

Thank you.

One cause of the problem is that not all cases are covered (eg, 0 s). I'd have used an elseif statement rather than evaluating each condition. In addition, I'd have also used an explicit range variable to handle t.

Exellent. This worked out for me. I was trying something similar, it seams I was missing 2Tsw/100 when defining t.

Many thanks Stuart

Actually Prime isn't as good in dealing with units as we often would like it to be - especially when it comes to plotting.

Primes quickplot feature only works unitless.

One way (not preferred) is to make the values unitless:

The preferred way is, as Stuart already had shown, to define a range variable for plotting. You can delete the end values on the axis as Prime will chose them appropriately itself. This also enables you to chose different units like the "ms" for the abscissa values in the following screenshot
