In the documentation of "int" (https://de.mathworks.com/help/symbolic/sym.int.html), I found the following statement which is not in agreement with my personal observations: "To approximate integrals directly, use vpaintegral instead of vpa. The vpaintegral function is faster and provides ...
I just want to clarify again. The integration order can not be changed. The integration order should be dy1 dz1 and then dx dy dz. That means first I need to do the double integral (dy1 dz1) of that function and then I need to do the triple integral...
MATLAB Online で開く Hi all, I have a question about using indefinite integral in Matlab with out using symbolic toolbox. I have to find the integral for the following function y@(x) = x + 2*sin(x) ; I know how to do this with a symbolic variable using the 'int' function. But...

Ok I got it. There is a function called evalfr to find frequency response of the TF at a given frequency. Create an array of omega,then create the frequency response array using evalfr. Then take the abs value of it and integrate w.r.t omega. ...
integral( @(s)(p(s)).^2./s,1,0.3)=-1.601 If instead I use int: ThemeCopy symsS g=matlabFunction(int( @(s)(p(s)).^2./s,1,S),'Vars', {S}); g(0.3)=0 Clearly the int is giving the wrong result, but I don't know why. This example comes from a much more complicate...
