Hello,
I have the following data:
x=[1 2 5 9 4 10 11 2 6]
y=[5 3 6 8 5 12 14 4 8]
I need to obtain a figure with:
  1. plot x y
  2. linear regression - y=mx+b
  3. Legend with linear regression equation y=mx+b
  4. R square value
I've seen this question: https://www.mathworks.com/matlabcentral/answers/38194-linear-regression
But still have not managed to achieve points 3 and 4.
thanks

Read about plotregression
x=[1 2 5 9 4 10 11 2 6] ;
y=[5 3 6 8 5 12 14 4 8] ;
plotregression(x,y);

Is it possible to increase resolution of m and b values? m has 2 digits after decimal point while b only has 1 which is inconsistent and insuficient.
It works but it is not quite what I was looking for. I was looking for something as excel provides:

nevertheless, thank you.
