Hi, i have a system of equations of the form Ax=b. with A and b known matrics, i calculates x using least square method. Now i want to calculate confidence interval on my estimated values in x. Any idea how should i proceed?

For the parameter confidence intervals in a linear problem, use the regress function. The ‘bint’ output will have them.

I am not certain that I understand what you are asking.
The ‘bint’ output is returned as an (Nx2) matrix. Just use it as it exists. No processing is necessary for it.
