error: This value must be a scalar :( HELP

[ycho-3]

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 @ycho-3, you need to do element by element multiplication for your equations to work. Also, you need to have a simple function for your e-e-t data (see the attached).

Yeah. So how did it bubble to the top again?

When I logged in this morning this was up, and a long list of Valery's posts dating back years (with the last post dated years ago.)

I think PTC's new improved web ware has a Y2.018K problem!  😉

Yeah, I didn't look at the dates, but now I see almost everything is really old material. These new forums leave a lot to be desired

As already pointed out, you need to vectorize the expressions.

When using minerr, do not calculate the error. Calculate a vector of residuals, resid:=fitting-experiment, and pass that to minerr. You will get better results.
