# regress

regression coefficients of two variables

### Calling Sequence

coefs=regress(x,y)

### Arguments

- x,y
real or complex vector

### Description

This function computes the regresion coefficients of two
variables `x`

and `y`

, both numerical vectors of
same number of elements `n`

. `coefs=[a b]`

be a
1x2 matrix such that `Y=a+bX`

will be the equation of
the ordinary least square approximation to our data.
