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).
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! 😉
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.
