non linear curve fitting using curve fitting VI

[diver81]

Hi guys. I am new to labview. I need to display this. If number 1 is greater than number 2 , display (number 1 minus number 2 ).Please help me out.

Start with some LabVIEW tutorials. The rest will fall into place.  Good luck.

I am unable to do it . I have tried many times. Is there any solution for this?

It's really trivial. Show what you have tried. You have also left unexplained what to do in false state (hint).

Ok . So I am unable to connect it to the subtract which I need it to display the value after my current load demand subtracts the value of the contracted capacity.

Can someone show me how?

Oh . If it is false . Then it will just display a 0.

Hi diver,

why do you want to connect the result of the comparison to your 2nd subtract node, when you want to calculate "Number1-Number2"?

You should program, what you have described before - actually you aren't doing this…

[Dennis_Knutson]

Everything you have is backwards. Don't you think the comparison should be done outside the case statement?

Hi, is there anyone out there who can help me, I am trying to generate a best fit line after taking some data from a DAQ 6008, after capturing  a transient response of the form y= a*(1-exp(-b*x))+c, i need to fit a best fit line, but keep getting error from the curve fitting VI, because is an iterative process, i keep getting this error input matrix is singular, any ideas?

Thanks

Hi ET,

there would ba a lot of people to help you once you create your own thread instead of hijacking a totally unrelated one…
