A Matlab script where, within a for loop, I analyze my CSV file. At each step of the loop, I obtain my polynomial function (string_polynomial), which I would like to import into Comsol. The Comsol model containing my geometry. In particular, within the physics .mf ...
Evaluating a matrix polynomialis not an efficient task when it is performed manually. But nowadays, it has become an easy task that can be performed in a very short amount of time using MATLAB’spolyvalm()function. This guide is going to present: ...
I am trying to create a newton polynomial in matlab. I have created the divided difference table and have my coefficients but when I try and create the second newton polynomial (x-x1) and multiply that by the second coefficient, those two x terms don't stay together and the x1 ends up...

May I ask how can I use aicbic in matlab for user defined functions? I tried to fit a set of data using different combinations of functions (sine, polynomial), I wanted to use aic/bic to test which one is a better function to model the data. Fromhttps://jp.mathworks.com/help/econ...
Sorry to bother you, but I have another question. I’m trying to plot another point on the polynomial. I know the x coordinate is 17.5, but I don’t know the y coordinate. Is there a way I could plot the x coordinate on the polynomial and use the informatio...

Open in MATLAB Online You could enter all of your equations at once in the form of a matrix, padding any polynomial equations with zeros if they are of a lower degree than the highest degree equation. ThemeCopy p=input('Polynomial equations in the form of a ...
polyfit doesn't return a value but a vector of coefficients of nDegrees+1; you need to allocate room for those as ThemeCopy polyCoeff=zeros(numFits,nDegree+1); where numFits is how many fits you're going to compute and nDegree is the degree of the fitted polynomial (1 ...
Example 1: Summation of a Simple Series Let’s start with a simple example: computing the summation of the firstnnatural numbers using vectorized operations. n=1:100;result=sum(n) In this example, we first define an arraynusing the colon operator1:100, representing the numbers from1to100....
