I am trying to get a polyfit curve from attached excel data, page 12. Data points read in fine and plot. I am getting a plotting error when I try to graph the polyfit function. Using Mathcad Prime 3.1. My goal is to generate an equation that approximates the data points for use in control scheme. I will need to display the coefficients as well. Thank you in advance for your assistance.
Solved! Go to Solution.
Sorry, look at page 12 for the error location.
Sorry but I see only 11 pages!
And I think you not correct plot two vectors and one function. See please my picture!
Sorry - I go to bet...
That particular plot I will be using piecewise functions later on for comparison. Not worried about it right now.
I am trying to replicate your plot but I am still unable. Plot is still failing and I do not understand why.
Nevermind, I figured it out. I had to create second array for polyfit plot points. Thank you. I appreciate all the help.
