plot(k,M,'.b')%画出这些离散的点,用蓝色表示 p=polyfit(k,M,1);%polyfit这个函数是指把离散的点fit成多条line f=polyval(p,k);%polyval这个函数是把我们拟合的函数加和,p是指拟合的线段(有多段,k是指变量),f是指p加和后的一个总的应变量的各个值。 hold on plot(k,f,'r') hold off grid ...
Once you have your plot, go toTools->Basic Fittingfrom the menu bar in the figure window. Then selectLinear. You will get the slope equation along with the best fit line on your plot. For additional information, refer to the following link: ...
fittedXxx = linspace(min(F), max(F), 200); fittedYyy = polyval(coeffsss, fittedXxx); plot(fittedXxx, fittedYyy, 'r-', 'LineWidth', 1); but the line was not completed I want the line to start from the the beginning/above of the first point. how I can do this?댓...
bf_B(i,n) = line_bf_re(i,n,1) - (bf_A(i,n)*sigma_n(i,n,1)); %Get the B in the line of best fit equation Ax+B. else if i==3 && n==1 f = polyfit(sigma_n(i,n,1:(end-1)), tau_n(i,n,1:(end-1)), 1); line_bf(i,n,:) = 0; line_bf_re(i,:) =...
What I cannot seem to do is create a line of best fit through this data. This line must be a straight line and I would like to know the parametric equation of this line. I would be most grateful if someone could advise me (a complete matlab beginner) how to go about this. Many th...
how to find the equation that best fit this curveWhat process produced these data? How best can you describe that process?Description: If you could only download one curve fitting tool to your laptop on a desert island, this should be it. [...]   The...
lsqnonlin (lsqcurvefit , fmincon) does not change the variables in an optimization process to find the best fitWe don't know if you get modified values for the array "force" from "ABAQUS" if the input vector "x" to "sim_res" is slightly changed ...
Herein, we introduce a user-friendly, high-efficiency, data fitting program named “Best Fit for Complex Peaks” (BFCP) based in Matlab®, written to deal with the above complexities in 2D XRD data. Matlab® has three advantages when comparing with other software: first, it is an ...
A line in the xy-plane with a standard form equation Ax + By = C passes through points (-6, 7) and (4, -1). If A is an integer greater than 1, what is the smallest possible value of the coefficient B? Reveal Answer: Problem Solving & Data Analysis 7. Multiple Unit Conversi...
MATLAB Online에서 열기 I have 1700 plot of data in graph. How do I plot the line of best fit? I stored the x and y data in table and the plot them. From the graph, I can see that the graph plotting is upwards. I have read other answers for this kind of question but ...
