How can I write a script for a default fit option for a gaussian fit?

I am trying to make a custom fit for my data using the Gaussian fit, but how do I go about setting that up. Currently I have this script:
ft = fittype( 'gauss1' );
opts = fitoptions( 'Method', 'LinearLeastSquares' );
opts.Lower = [-Inf -Inf -Inf];
opts.Upper = [Inf Inf Inf];
[fitresult, gof] = fit(xData, yData, ft, opts );
When I enter "opts.MaxInter = (600);" it gives me an error and does not include it in my fit options. How can I set up the MaxInter, and the other values that are in the fit options in my script. I appreciate any help!!

Also give code to generate xData and yData so we can run your code.

My data points are currently arbitrary. My xData is [2, 1.35, 0, 1, 2, 3.4, 4, 4.5, 6.3, 8]. My yData is [0.05, .3, .7, 1.9, 2, 2.5, 3.7, 2.2, 1.5, .5]. I know it can be a simple fit, but I just want to get used to it when I have more numbers for the data.

See attached demo to fit a Gaussian shape to some noisy data that roughly traces out a Gaussian shape.
