Discretize your function over the range to more than 4000 points (say) and store it in a vector. Then use ifft(vector). You'll get the coefficients (if you want 1000, get the first 1000). Suppose you have a cosine transform. f=f0+2*f1*cos*(w*x)+2*f2*cos(2*w*x)+2*f3*cos(3*w*x)+... ifft will...

Hello there, You'll have to excuse me because I'm not using the greek symbols. (a) r<R, int(E.dl)=-d(B.Area)/dt (definition of induced emf) take loop around E.2*pi*r = -pi*(r^2)*mu*n*I*omega*cos(omega*t) E= -(mu*n*I*omega*r*cos(omega*t))/2 is the induced field inside solenoid. Your answer...

Hello all, I have a MATLAB Ax=b problem where A is a matrix generated from the eigenvalues/ vectors of another matrix, which is conditioned well (rcond >eps). A is around 5000 X 5000, complex, has its first half filled with values from the other matrix, and the other half has very few...
