Origin Ver. and Service Release (Select Help-->About Origin): OroginPro 9
Operating System: Win7
I have a specific function (for example : f(x)=a+b*x+c*x^2)and I'd like Origin to generate the values of this function on the specific interval. How do I do this?
Thank you. |

Hello,
There are a couple of ways to do it in Origin.
1. Simulate Curve:
Origin has many built-in functions. The following Parabola is one of them.
You can choose Analysis: Fit: Simulate Curve...
In the dialog that opens, you can choose Category: Polynomial.
Function: Parabola
Then specify the a, b, c values, x type and range, etc.
The simulated curve will be created and a new hidden workbook is created as well. You can right click the plot created and choose Go to BookN to see the x and y data.
2. Function Plot.
Origin supports creating 2d, 3d, 2d parametric, 3d paramatric function plots.
You can choose
File: New: Function Plot: 2D Function Plot menu to define the function and create function plot as well.
After function plot is created, you need to right click the plot in graph and choose Make Dataset of F1 for example. Then right click the data plot in new graph and choose Create Worksheet F1_C1 for example to get the Y dataset. The interval info. is in the i icon of the Y column. You can right click the Y column and choose Show X Column to see x values.
Thanks, Snow
