MATLAB Online에서 열기 Hello everyone, and pardon my stupid question; So, I have this polynomial equation: 테마복사 I = (z*t*N)/2 + b*((z*N))^(1/d) - U*A*h + P*h + R*A - L - (t*N)/2 After setting the variables ("syms z A P h b N U R d L...
1i is used to ensure it isn't confused with a variable named i that you might have in the workspace. I.e., 1i is always sqrt(-1), whereas just i might be sqrt(-1) or a variable that you created named i. It is common to see 1i used in MATLAB for sqrt(-1) because it...
is throwing error as MATLAB is not able to resolve "x1- grad_x1*t". So make sure bothx1andgrad_x1are of same size or "x1-grad_x1*t"should make sense like we can subtract 2x2 matrix from 1x2 like this : symsx1 x2 p = [x1,x2;x2,...
Open in MATLAB Online Hi I'm currently working on a project and am trying to solve for x. Here is the code I am using: ThemeCopy h = 0.181356; syms x; S = (x^4)-(h/x)^2 == (h/14)^2; SS = solve (S,x); pretty (SS) It's pretty simple but when I run the scr...
You can use "who" to find out what symbols are accessible in the current workspace, and you can use class() to find out which class the variable is; or you can use isa(varible, 'sym') to test if it is a sym

expressions to matlab functions (i.e. Im - imag, Re-real) and I have encountered an 'I' term in the output expression. It is not the imaginary 'i' because that also exists in the expression and it is scalar therefore it can't be the identity matrix...does anyone know what it deno...
