I am trying to plot a graph between Power and speed. Unfortunately, I have data for for only high speed but I do know that the relationship between power and speed of a ship is a cubic curve. So, I decided to use the curve fitting tool app in MATLAB to predict power at lower speeds. However, I am having a hard time exporting the plot exactly as it is from curve fiiting tool to MATLAB. I am not able to get the data for lower speeds. Please find attached the plots in MATLAB and Curve Fit. Tool.
How can I export the plot as it is to MATLAB so that I have power for lower speeds?
