histfit help about fitting equation parameters

Recently, I used histfit to analyze my data, but I failed to obtain the fitting equation parameters. For example,histfit(t2,30,'exponential'), through this, a histogram and fitting curve will be obtained. The fitting curve should be y=a*exp(b*x), what is the value of a and b? Does anyone know the code to get the values of 'a' and 'b'?

The histfit function fits a distribution to data, not data to a function. You have to use the Statistics and Machine Learning Toolbox nlinfit function (or similar techniques) to fit your function to data.
