Yes. Use sprintf() to create a string with the equation in it. Then use text() to place that text onto the graph/plot wherever you want it. 댓글을 달려면 로그인하십시오. 카테고리 MATLABGraphics2-D and 3-D PlotsLine Plots ...
MATLAB Online에서 열기 Yes, you need to call polyfit with the output arguments, and then use those output arguments to plot the line. Here is a simple example: % Simulate some data N = 20; x = rand(N,1); y = 2 + 3*x + 0.5*...
Hi, I divided the datapoints of a fault scarp profile into three datasets for the footwall, scarp slope and hanging wall and plotted the respective best fit lines. What is the easiest way to just extend the length of the best fit line for the scarp so that it crosses the best fit line...
how to return the best fitI am fitting a function nonlinearly using the lsqnonlin function. I have used the [x, res] to return the parameters (i.e. x) and the residual (i.e. res).Just call the objective function with the x-vector of optimal paramters. It will return the best fit...
So I want to fit different models to X and Y for each ROI and get a decision, which model fits best. I still struggle to get this working as I am unsure whats the best way to go and how to get this implemented. I think a Bayesian Model Selection approach would be suitable ...
There is an obvious singularity at x == 0. This suggests that a polynomial model will be useless, or at best poor. Polynomials do not have singularities, so you would need a high order polynomial. (When you try to fit a polynomial to a function with a singularity, it will do str...
I need to plot it first and divide it into two sections and fit straight lines separately. Then get the intersection of those straight lines and get the co-ordinate points. 1 Kommentar darova am 5 Mär. 2020 Can you show your data? Do ...
Open in MATLAB Online Interesting that nobody has noticed that what you are trying to fit is not in fact a gaussian model! This is most likely why you are having problems with the fit. Here is the line you wrote: ThemeCopy modelfun = @(p,x)(p(1)+...
I want to fit the above data using the implicit function: a-(1/k)*(-1+1/k+2*ln(-1+1/k)-1/(-1+1/x))-t=0 (a and k are the parameters to be calculated, x is as a function of t). But I do not know how to edit program code. Can you help me address this problem?
Open in MATLAB Online hi all i have set of points and class + -1 i want to calculate the line i want to use 1. direct linear algebra (inverse matrix , cross product) 2. use gradient descent i dont want to use the svm function or quadratic programming ThemeCopy x=[ 1 2 ; 3 ...
