Why this error comes? Kindly fix it

Not enough input arguments.

Error in SVMCalculation (line 4)

mag = (Mag/max_phase)*ts*1.15;

Answer 1

[Sabin]

This function will compile if change either change Seq in the first line into seq or seq into Seq everywhere. I believe the error seen is due to incorrectly calling the function by not providing all input arguments. I cannot comment if the algorithm is correct as I was not checking it.
