Lines in RPN mode | HP 49g specification

data sets (x,y), stored in columns of the Σ DAT matrix. For this application, you need to have at least two columns in your Σ DAT variable.

For example, to fit a linear relationship to the data shown in the table below:

xy 0 0.5 1 2.3 2 3.6 3 6.7 4 7.2 5 11

•First, enter the two columns of data into variable Σ DAT by using the matrix writer, and function STOΣ .


•	To access the program			, use the following keystrokes:
		The input form will show the current Σ DAT,

•	To obtain the data fitting press		.	The output from this program,
	shown below for our particular		set, consists of the following three
	lines in RPN mode:
