Hello,
I'm using origin 7.0 SR2 and I'm trying to input this equation
A=F*0.5*(Kd+n*Ht+Dt-((Kd+n*Ht+Dt)^2-(4*n*Ht*Dt)^0.5)
I am trying to fit some data to figure out what F and Kd are.
Ht is my x axis,
A is my y axis,
Dt is always 0.5
n is always 1
F and Kd are my unknowns...
I'm kind of new to origin, but when I input this equation and compile it, it's giving me 2 errors saying declaration in variable name and syntax error.. I was wondering if someone could help me figure out what the problem is.
Thank you,
|

Hi Sarsour,
I have tried to compile your function both both in version 8.6 and in 7.5; and got no errors. I suggest you to check the definition carefully. Especially:
Function Type: Origin C
Parameters: Dt,n,F,Kd (comma-separated)
Indep. Var: Ht
Dep. Var.: A

Oh it's working now! I think there was a problem in the program or something.... I tried a new worksheet with it and it worked.
Thank you for your help! |

Sorry I meant to put
A=F*0.5*(Kd+n*Ht+Dt-((Kd+n*Ht+Dt)^2-(4*n*Ht*Dt))^0.5)
but I'm still getting those two errors.
Thank you,
