Hiii ,i need some help in matlab concerning programming pseudo Spectral method for Volterra equation i have all the script but when i check the solution i found i message error Warning: Cannot find explicit solution. > In solve (line 316) In HMM (line 350) La valeur numérique de x lorsque t = 0.0625 est :
Which other computational software have you utilized for solving numerical problems? The logical skills required for problem-solving are generally transferrable to MATLAB environments when addressing numerical problems.
@Hamza, maintain your determination; your goal is within reach already. Encourage yourself to accomplish the task in the forthcoming days. Assuming you possess a mathematical background (which I presume you do), dare to make conjectures enabling the transformation of the Volterra equation into a special class of nonlinear equations for which explicit solutions are known.
Subsequently, revise your query accordingly and share the MATLAB script in this forum.
eqn1_substituted == 0 , e.g., is a vector of 3 equations in a scalar variable x.
Do you want to solve the three equations separately and get three different x-values ? I did this in your code for eqn1_substituted(1) == 0, thus for the first equation. Maybe there are other solutions apart from x = -104.60...
I don't know anything about the mathematical background of your code and won't dive into it - I just wanted to show you that the "solve" command will not work because you have 16 equations in 1 unknown.
So what we can try to do is to find technical errors in your code, but we won't be able to rectify the mathematics.
