Trying to solve a systems of 3 equations with 3 unknowns by means of SOLVE BLOCK and MINERR function. (or find). It doesn't provide any error message but it seems not to calculate any root; it simply provides the three guessed values as the results without running any iteration.

Hi,

I have carefully checked your work, It is correct.

I also get the wrong answer compared to the original.

I trust someone from PTC is watching this thread and can see the errors in Prime.

Cheers

Terry
