[Numpy-discussion] polyfit on multiple data points

2009-04-13 Thread Mathew Yeates
Hi, I understand how to fit the points (x1,y1) (x2,y2),(x3,y3) with a line using polyfit. But, what if I want to perform this task on every row of an array? For instance [[x1,x2,x3], [s1,s2,s3]] [[y1,y2,y3,], [r1,r2,r3]] and I want the results to be the coefficients [a,b,c] and [d,e,f] wh
