MATLAB Online에서 열기 hadi, you need to define x as a symbolic variable 테마복사 syms x y f = @(x,y) x^2 + y; f = sym(f); out = subs(f,x,2) out = y + 4 댓글 수: 1 hadi 2015년 3월 17일 Thank you so much I really appreciate your help...
The space in these expressions give me results differents.Do not eval() MuPAD expressions, such as are returned by sym() or subs(). MuPAD and MATLAB use different syntax rules and different operators. If you want to convert a MuPAD expression into executable MATLAB form, use matlabFunction...
If you have a large amount of data, tens of millions of rows of data, how can you use IF statements in MATLAB to find specific data points that spike above a certain threshold? Lets say for example you have a load of capacitance data against time. And you ...
Open in MATLAB Online use subs() for example, to leave t alone and put in pi for the x variable subs(d2v_dx2,[x,t],[pi,t]) or to substitute for both variables subs(d2v_dx2,[x,t],[pi,pi/2]) Sign in to comment. More Answers (0) ...
You could usecoeffsto see if you can isolate common factors, however I doubt that the result would be in any way illuminating. サインインしてコメントする。 参考 MATLAB Answers place array in a matrix 1 回答 I have two symbolic polynomials of the same order. One of them also has symb...

Open in MATLAB Online Do not eval() a symbolic formula. If the formula contains symbolic variables then use subs() on it; if the formula does not contain symbolic variables then use double() to represent the number a double precision. The general solution for the above is ThemeCopy -ho...
2. When calculating the volume around the y-axis, you need to solve “y = f(x)” for “x”. This can return multiple solutions, especially for trigonometric functions. This leads to the error youindicatedin “Output 1”.Use only the principalvalue to get a manage...
Open in MATLAB Online Currently the only option to resolve this is mentioned in the error message itself. The diagnostic option cannot be set toNoneorWarningusing the Configuration UI, which is why you need to use the Simulink API: set_param(bdroot,'M...
matlab syms x f = x^2 + 3*x – 2; df = diff(f, x); The variabledfnow stores the symbolic expression of the derivativef'(x). We can evaluate this expression at specific values ofxusing thesubsfunction. For example, to evaluate the derivative atx = 2, we can use the following co...
