what is PAR on MATLAB?

i have this result below my question: what is PAR and Y at this result?

What is PAR on Matlab? i have this result:

*par = *

sse: 0.0027

rsquare: 0.9907

dfe: 8

adjrsquare: 0.9895 rmse: 0.0184

what is par?

and what is Y on this result?

*Y *=

General model:

Y(x) = 1-exp(-a*x^b)

Coefficients (with 95% confidence bounds):

a = 0.1836 (0.1563, 0.2109)

b = 0.8199 (0.7382, 0.9015)

First, par and Y here appear to be previously-defined Matlab variables, not built-in functions.

It looks like the outputs from the 'fit' command in the Curve Fitting Toolbox. par is the goodness-of-fit outputs, and Y is the model. See:
