Gents,
I have an third order polynomial (calculated from an function of an item):
y = ax^3 + bx^2 + cx + d, where a, b, c, d are well-known constants.
x = ?
The parameter y is connected to LabView I/O port and it is measured. I need to calculate value of x for each time-step.
I know that I will get three solutions for each calculation. Does anybodu know how it can be implemented in the LabView?
eks:
y = 5*x^3 + 7*x^2 + 3*x + 2, where a=5, b=7, c=3, d=2
x = ?
Regards
Hariss
