Hello,
I am an absolute beginner in MATLAB. I want to fit my attached data as per this equation.
(-0.00789+0.06769*sqrt(x+0.021159*(x^2)))
In attached data------ Y axis = data.mat
X axis = ED.mat
Many thanks!

The equation you have written there has no parameters. It has only constants and the data.
But if each of those constants (e.g. 0.06769) is actually a parameter that you are hoping to find via fitting, then I suggest using the fitnlm function from the Statistics and Machine Learning Toolbox.

Sorry, I've never heard of that technique, and a quick google search did not turn up much for me.
Next time you ask a question, you might want to put more detail like that into it. It saves everyone's time.
