On page 4-7 of curvefit documentation _cv_IterData is said to be 2x1. However it is 3x1 with the first element the number of iterations, and the second appears to be time, and the third is an integer. What is the third number? A small example is this.
11 0.00369999999995343 1 10 0.00291666666666667 1 10 0.00328333333336438 1
Thanks.
