Open in MATLAB Online Hello, I have the following equation. ThemeCopy cos(x) == 0 I want to get two or more possible solutions for the above equation which are 90, 270, and so on. The solve function returns the first solution only. This technique is important for me to calculate ...
From the series:Solving ODEs in MATLAB An ordinary differential equation involving higher order derivatives is rewritten as a vector system involving only first order derivatives. The classic Van der Pol nonlinear oscillator is provided as an example. The VdP equation becomes stiff as the parameter ...

Please how can i solve a quadratic equation analytically in MATLAB. Like x(t)=t.^2+4*t+5 and display the answer in the form (t,x) when t=0:0.1:1? Also, how can i plot the result in MATLAB? Thank you. 댓글 수: 0 ...
With element-wise operation (multiplication, in this case) you perform operations element by element. The very same concept applies to your equation.It

Solving and Optimizing in Matlab 1Note that you can copy code from the pdf and paste into a Matlab editor window to try out the code, or look for the code in Matlab/SuppExamples.A single equation can be solved numerically for a single variable using 'fzero'. If you have the optimi- ...
I think the following does all that you want. My implementation of the legend is cumbersome, but works!
Since the bottom row contains all zeros except for the last entry, the equation does not have a solution. In this case, pinv(A) returns a least-squares solution. Overdetermined systems Similar to Least Squares Solutions. Omitted. Underdetermined Systems ...
