The thing i am looking for is in Excel, however, i would like to find it 
in MATLAB to be honest. I will try to explain that on Excel example

In EXCEL there is a formula called LINEST and has the form below

LINEST(knowm_y value cells, known_x values cells, CONST, STATS)

This formula produce more or less such results as:
SLope Coeff          Point Of intercept
Slope Coeff Error    Point Of Intercep Error
...
...
...

I dont know that yet but i believe in produces results with 95% 
confidence intervals. The other values are not important here at the 
moment. The Slope Error is the thing i am looking for in MATLAB.
Can someone please be so kind and help me to find/understand that.

Regards
